Question
An ac voltage is applied to resistance R and an inductor L in series. If R and the inductive reactance are both equal to 3Ω, the phase difference between the applied voltage and the current in the circuit is
Options
A.π / 6
B.π / 4
C.π / 2
D.zero
Solution
Here, R = 3 Ω
Inductive resistance, XL = 3
The phase difference between applied voltage and the current in the circuit is
tan φ =
φ = tan-1 (1) or φ =
Inductive resistance, XL = 3
The phase difference between applied voltage and the current in the circuit is
tan φ =
φ = tan-1 (1) or φ =
