Consider the RL circuit in Fig. When the switch is closed in position 1 and opens in position 2 , electrical work must be performed on the inductor and on the resistor. The energy stored in the inductor is for the resistor energy appears as heat. a. What is the ratio of P_(L)//P_(R ) of the rate at which energy is stored in the inductor to the rate at which energy is dissipated in the resistor? b. Express the ratio P_(L)//P_(R ) as a function of time. c. If the time constant of circuit is t , what is the time at which P_(L) = P_(R ) ?

A circuit contains two inductors of self-inductance L_(1) and L_(2) in series (Fig) If M is the mutual inductence, then the effective inductance of the circuit shows will be

The reactance of a circuit is zero It is possible that the circuit contains (i) an inductor and a capacitor (ii) an inductor but no capacitor (iii) a capacitor but no inductor (iv) neither an inductor nor a capacitor .

The current in an L - R circuit in a time t = 2L / R reduces to-
