What happens when a capacitor is charged?
Once the capacitor is charged, turn off the generator and nudge the string suspending the metal ball such that the ball touches the insulated plate. Once the ball touches the insulated plate, it will begin bouncing between the plates, creating a “bell” effect.
How does a capacitor work?
The capacitor has a moving and a stationary plate, both 260mm in diameter. The stationary plate is separated from the frame by an insulator, preserving its electric charge. The moving plate is connected to the base, and moves using a micrometer screw. You can adjust the spacing from 0 to 70mm, reading the distance precisely to 0.1mm.
Why do ping pong balls move through a capacitor?
The rubber barrier is the dielectric in the capacitor, the ping pong balls are charges, and the tube is your conductor. You can see that by applying a force (voltage potential) on one side of the conductor will still cause movement of the charges, but they will not actually flow through the capacitor.
What happens when a capacitor is connected to a voltage supply?
When capacitors in series are connected to a voltage supply: because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.
Why do capacitors have a high leakage resistance?
As you know, capacitors consist of two "plates" separated by an insulating layer which has a high leakage resistance. The electrostatic field between the plates means that when an electron enters the right plate it forces an electron off the left plate.
How a ball is pushed away from a negative charge?
Like charges repel, so the ball is pushed away from the negatively charged plate by an electric field. The ball is also attracted to the positive charge in the neutral plate. Once the ball touches the grounded plate, it gives its excess negative charge to the grounded plate and becomes neutral.
