Question 1
For a circuit show on Fig B1, what is the rate of change of the current in the inductor when the total current in the circuit is 0.50 A? (L = 10 mH, R(1) = 10 ohm, R(2) = 20 ohm, V = 12 V). In the figure the resistors of the circuit are in series.
Ans: 200
[itex](di/dt = V/L(e(-Rt/L)))[/itex]
[itex](i = V/R(1-e(-Rt/L)))[/itex]
I tried to find the time at which the current was at .50 A and the using that time to plug in the differential equation to find the rate of change in the current.
