Question

The INCORRECT statement is

• A. The direction of eddy currents is given by Lenz' law.
• B. A choke coil is a pure inductor used for controlling current in an A.C. circuit.
• C. The r.m.s. value of A.C. current is √2 times the peak value of A.C. current.
• D. Quality factor is a measure of sharpness of resonance in A.C.circuit.
• E. Magnetic field energy stored in an inductor of inductance L is $\frac{1}{2}LI^2$.

Answer 1

Answer: (C)

The r.m.s. value of A.C. current is √2 times the peak value of A.C. current.

Answer 2

The correct option is (C) : The r.m.s. value of A.C. current is √2 times the peak value of A.C. current.
