Q3. A relay has a resistance of 300 Q and is switched on to a 110 V d.c. supply. If the current reaches 63.2 percent of its final steady value in 0.002 second, determine (a) the time-constant of the circuit (b) the inductance of the circuit (c) the final steady value of the circuit (d) the initial rate of rise of current.
