(i) In an inductor current logs behaind the voltage by a phase angle of π/2 .
(ii) In a capacitor current leads the voltage by a phase angle of π/2 .
Class 12 Physics Chapter 7 Alternating current Session 2024-2025.
A reactive element, in an a.c. circuit, causes the current flowing (i) to lag in phase by π/2 , (ii) to lead in phase by π/2 with respect to the applied voltage. Identify the element in each case.
