The winding of an electromagnet has an inductance of 110 mH and a resistance of 5.5 . When it is connected to a 110 V, d.c. supply, calculate (a) the steady state value of current flowing in the winding, (b) the time constant of the circuit, (c) the value of the induced e.m.f. after 0.01 s, (d) the time for the current to rise to 75% of it's final value, and (e) the value of the current after 0.02 s
