Question

6.An LR circuit consists of a resistance of
50 and a coil of inductive reactance
12022. If the circuit is connected across
260 volt ac mains, the current in circuit is :
26
13
12A
2 2 0 A 3 25 A 4 13A​

Answer 1

Explanation:

The term L/R in the equation is called the Time Constant, (τ) of the RL series circuit, and it is defined as time taken by the current to reach its maximum steady state value and the term V/R represents the final steady state value of current in the circuit.What is the power factor of an LR circuit? What will be the power factor of an RC circuit? Two circuits having the same numerical ohmic impedance are joined in parallel. The power factor of one impedance is 0.6 lagging and that the other is 0.866 leading.
