Customer ServiceOnce charged to its maximum possible Q, the capacitor's plates are separated by a factor of four (that is, the distance between the plates is quadrupled) while the capacitor is kept hooked to the power supply. As a consequence of this change in geometry:
The true power in a capacitor is zero. Answer: Option A Q 18. A 12 kHz voltage is applied to a 0.33 μF capacitor, and 200 mA of rms current is measured. What is the value of the voltage? Answer: Option A Q 19. The ohm is the unit of capacitance. Answer: Option B Q 20. When the plate area of a capacitor increases, Answer: Option A Q 21.
The capacitance depends upon the area of the plates, dielectric material, and distance between the plates. The capacitance is directly proportional to the relative permittivity of the dielectric medium and the area of the capacitor plate, but inversely proportional to the distance between the plates.
Capacitance is the ability of a body or a capacitor to hold the charge. Capacitance is denoted by C and it is measured in the unit called Farad. Capacitance C = Q/V, Q – charge stored in the capacitor, V – voltage across the plates. Hence, the capacitance of a capacitor is the ratio of stored charge to the potential difference across the plates.
Solution: After a long period of time, the accumulated charge on the capacitor's plates will produce a voltage across the capacitor that is equal to the voltage across the power supply. At that point, there will no longer be current in the circuit.
