Q: You may, if you wish, disconnect only 1 of the 2 leads from the circuit. This information should be printed on the outside of the capacitor as well. Look for a number followed by a capital “V,” the symbol for “volt.” For a 25V capacitor, you could use a voltage of 9 volts, while for a 600V capacitor, you should use a voltage of at least 400 volts. Let the capacitor charge for a few seconds. Be sure to connect the positive (red) lead from the voltage source to the positive (longer) capacitor terminal and the negative (black) lead to the negative (shorter) terminal. The greater the discrepancy between the capacitor’s voltage rating and the voltage you’re charging it with, the longer it will take to charge. Generally, the higher voltage of the power supply you have access to, the higher the voltage ratings of the capacitors you can test with ease.  Connect the positive(red) lead to the positive (longer) terminal and the negative (black) lead to the negative (shorter) terminal. This should be close to the voltage you supplied the capacitor with. If it isn’t, the capacitor is no good. The capacitor will discharge its voltage into the voltmeter, causing its reading to drop back to zero the longer you have the leads connected. This is normal. Only if the initial reading is much lower than the expected voltage should you be concerned.
A: Disconnect the capacitor from its circuit. Check the capacitor’s voltage rating. Charge the capacitor with a known voltage less than, but close to, its rated voltage. Set your voltmeter to read DC voltage (if it’s capable of reading both AC and DC). Connect the voltmeter leads to the capacitor. Note the initial voltage reading.

Q: Regulation water polo players are not allowed to push off of the wall or sides of the pool. You must tread water the entire time. This is incredibly exhausting, but good players use a rounded, more efficient motion to stay afloat:  Bend your knees roughly 90-degrees as if you were sitting. Keep your legs slightly wider than shoulder width apart. Rotate your right leg counterclockwise. Rotate your left leg clockwise. Time your legs so that they alternate fluidly. They are called the center forward, and sit about 2 meters (7 ft) outside of the goal to cause confusion and take close-range shots. When you get the ball as a center your goal is to quickly turn and fire a shot off.  Centers take the bulk of physical play, and must have the best endurance and strength. Centers are also called "Hole Sets" by some coaches. You should have a line of three players in front of the goal on offense -- two wings on the sides and one center forward in the middle. A wing's goal is to take long range shots, as well as pass back and forth with the center to make space for a shot.  Wings need to have quick, accurate, and long-range shots. Remember that you cannot use the walls to push off. You should be a few meters in from the wall as a wing. Flats are great passers and long-range shooter. They swim at the goal to draw defenders, which hopefully opens up space for the center forward to get free. They must race back on defense when the ball is turned offer. Flats tend to be very quick, very mobile swimmers. This is your "Point" player. They are the first ones back on defense, and the main passers of the team, seeing and setting the entire offense. They rarely shoot, instead looking for the best, most dangerous passes. The movement of your perimeter players (everyone but the center forward) is what opens up shots and breaks down good defenses. This can include swapping positions, crashing towards the goal, or rotating around the pool. The center forward can move, but they are generally needed to keep the essential space in front of the goal open in case of deflected shots or sudden shooting opportunities. You simply slide your formation down the pool on defense. The point guards the opposing center forward, and the center forward guards the point. Your wings will cover their flats and your flats cover their wings. In general, you will play either man to man or zone defense:   Man to Man Defense: Each player follows their match around the pool, no matter where they go.  Zone Defense: Each player stays in their position, trading defensive marks as the other team changes positions. If the opposing team has a very good center forward, this position is sometimes double-teamed, leaving the offenses point player alone.
A: Use the "eggbeater" kick to stay afloat while conserving energy. Hold one player up in front of the goal to direct your attack. Place two players at the 2-meter line, on either side of the goal, as Wings. Place your two "Flats" on the 5-meter line, between the wings and center. Keep one player behind everyone, near the half line and in the center of the pool. Keep your wings, point, and flats moving to confuse the defense. Flip the offensive formation on defense.

Q: If you have an earlier version of macOS that still has iTunes installed, click the music note icon on the Dock to open iTunes. If you're using Windows, click iTunes in your Start menu.  If you're using macOS Catalina, see the Syncing with Finder method instead.
A: Open iTunes on your computer.

Q: You can use any cream you want, as long as it adds moisture, smoothness, and shine. You can even use a small amount of conditioner, if you want. Apply the product all over you hair, but focus it on the ends. You're hair should be damp enough so that it is still wet but no longer dripping. A side part would look especially cute with beach waves, but you can do a center part too. Use the handle of a rat-tail comb to make the part even and clean. You will need vertical two sections on each side of your hair. If you have longer hair, you might be able to get away with just two sections, one on each side of your head. Secure the buns with small hair ties or bobby pins. Make sure that they are secure and won't come out. For tighter waves, twist each section into a rope braid first, then twist it into a bun. If you created a side part, consider leaving a small wisp of hair at your hairline out of the buns. This depends on how well your hair holds a curl. It also depends on how tight your want the waves to be. If you want really loose or relaxed waves, you can skip this step. How long this takes depends on how thick and porous your hair is. It could take an hour or it could take overnight. You can speed things up by using a hair dryer, but you need to be sure that your hair is dry inside too.  Keep in mind that using a hair dryer will not ensure that the inside of the bun is dry. If you want to speed up the process, it's best to sit under a hooded dryer. If you left a wisp of hair out of the buns, twist it into a delicate rope, then drape it behind your ear. Your hair should have taken on a loose, wavy shape. Again, your buns must be completely dry before you take them out, otherwise the waves won't hold. If you coiled the wisp of hair behind your ear, you can uncoil it now. Your hair is likely clumped into two big waves (or four if you did four buns). Run your fingers through your hair, shaking them a bit. This will help break the waves up into smaller waves. It will also help add volume and a messy, beachy texture. This really depends on how well your hair holds a curl. If you have thick or curly hair, you may not need any hairspray; if you have straight or fine hair, a light misting may help the style hold longer. Here are some other finishing tips, depending on the look you want:  Spray your hairbrush with sea salt spray, then comb it through your hair for volume. This will make your hair appear fuller. Apply some dry shampoo to the roots for more texture. Tease your hair at the crown for even more volume. Tame flyaways with a styling cream, serum, hairspray, or a little bit of conditioner.
A:
Apply a styling cream to damp hair. Part your hair as desired. Divide your hair into four sections. Twist each section into a mini bun. Mist your hair with a lightweight hairspray, if needed. Allow your hair to dry completely. Undo the buns once they are dry. Gently break up the waves. Set the style with hairspray, if desired.
