Explanation:
Given Ac current of amplitude 2 mA and frequency 2 KHz is passing through an ideal capacitor of capacitance 0.5 pF. The power dissipated by this capacitor is?
- We need to find the power dissipated by this capacitor.
- Power dissipated in an ideal capacitor is always zero.
- So Power = VI cos φ
- For an ideal capacitor φ = 90 degree
- Therefore cos φ = cos 90 degree
- cos φ = 0 (since cos 90 = 0)
- So power dissipated P is equal to zero.
