Customer ServiceThe 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.
Answer-12: The capacity of a capacitor is numerically equal to the quantity of charge which must be given to the condenser in order to maintain the unit potential difference between the plates. Question-13. On what factors the capacity of a capacitor depends?
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.
Answer-11: Capacitor is a device for storing charges. It consists if two metal plates placed parallel with a dielectric or an insulating medium in between them. Question-12. Define Capacitance of a Capacitor?
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.
Brief the Capacitor behavior in AC and DC circuits. If a DC voltage is applied across a capacitor, the capacitor charges and voltage across it reaches the maximum value which is equal to the supply voltage. At the initial time the current will be maximum and once the capacitor is fully charged the current flow will be approximately equal to zero.
