0<phase difference for R-L circuit < π/2
A current I flows along the length of an infinitely long, straight, thin walled pipe. Then
The phase difference between the alternating current and emf is π/2. Which of the following cannot be the constituent of the circuit?
Alternating current can not be measured by D.C. ammeter because
In an LCR series a.c. circuit, the voltage across each of the components, L, C and R is 50 V. The voltage across the LC combination will be
