Step 1

The initial energy stored in an inductor is given by the formula: E = 0.5 * L * I^2, where E is the energy stored, L is the inductance, and I is the current flowing through the inductor. Given that the inductance L = 8 mH = 8 * 10^-3 H and the current I = 120 V / Show more…

The switch in the circuit shown in Fig. 2. has been closed for a long time and is opened at t=0.What percentage of the initial energy stored has been dissipated in the 2Omega (R_(b)) resistor 10ms after the switch has been opened? h. What percentage of the initial energy stored has been dissipated in the 2Omega (R_(a)) resistor 10ms after the switch has been opened? i. Verify the value of the energy dissipated in the equivalent resistor (Question e) and the total energy dissipated in R_(6Omega ),R_(a),R_(b)10ms (Question f,g,h ) after the switch has been opened. 2 0 WW 6 WW U 9 120 V 20 8 mH 32032 0 Bp Fig. 2.
