Free complete solution to this question: " Growth and decay of current in lr circuit"

Solve problems involving current growth/decay in an L-R circuit and voltage growth/decay in a C-R circuit.

(a) The winding of an electromagnet has an inductance of 3H and a resistance of 15Ω. When it is connected to a 120V, d.c. supply, calculate:

(i) the steady state value of current flowing in the winding,

(ii) the time constant of the circuit,

(iii) the value of the current after 0.3 s

(b) A 15μF uncharged capacitor is connected in series with a 47 kΩ resistor across a 120 V, d.c. supply. Plot the capacitor voltage growth characteristics by preparing a table of data . From the graph,

determine the capacitor voltage at a time equal to one time constant after being connected to the supply. Also, find the time for the capacitor voltage to reach its final steady state value.
