Explanation / Answer

ANS:E

(i)The instantaneous value of the current is the same everywhere in the circuit.

True because its series circuit and current is same in series circuit
(ii)The voltage drop across the resistor is in phase with the current.

True because V and I are always in phase in resistor

(iii)The voltage drop across the capacitor trails the current by 90 degrees.

True because current leads voltage in capacitor circuit
(iv)The voltage drop across the inductance leads the current by 90 degrees

True because voltage leads current in capacitor circuit
