Match List-I with List-II

List-IList-II
A) Phase difference between current and voltage in a purely resistive AC circuiti) π2; current leads voltage
B) Phase difference between current and voltage in a pure inductive AC circuitii) zero
C) Phase difference between current and voltage in a pure capacitive AC circuitiii) π2; current lags voltage
D) Phase difference between current and voltage in an LCR series circuitiv) tan1XCX1R

Choose the most appropriate answer from the options given below:

a
A-iii;B-iv;C-iii;D-I
b
A-ii;B-iii;C-iv;D-i
c
A-i;B-iii;C-iv;D-ii
d
A-ii;B-iii;C-i;D-iv

detailed solution

Correct option is D

In “C” circuit, current leads by  π2 with emfIn “L” circuit, current lags π2  with emfIn LCR series circuit , tanϕ=XL-XCR
