- A circuit that has the only capacitor is known as a purely capacitive circuit.
EXPLANATION:
- Capacitive reactance is defined as the resistance offered to the flow of current by the capacitor.
- It is denoted by letter XC.
- The capacitive reactance is given by:
Where C = capacitance and ν = supply frequency
- Capacitive reactance is inversely proportional to the supply frequency, i.e.
- If the frequency increases, the capacitive reactance decreases and vice-versa.
- Alternating emf in the circuit is
- Current in the inductive circuit is –
- From above it is clear that current leads the voltage by π/2.
