Answer 2

The given circuit is pure capacitor.

• in a pure capacitor the resistance is zero and therefore its impedance is negative which is its minimum value.
• In a pure capacitor current leads the voltage by 90 degrees and therefore has the maximum value of current
• The instantaneous current is directly proportional to the rate of change of instantaneous voltage in a pure capacitor.
