Question 1 1. The problem statement, all variables and given/known data 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 2. Relevant equations [itex](di/dt = V/L(e(-Rt/L)))[/itex] [itex](i = V/R(1-e(-Rt/L)))[/itex] 3. The attempt at a solution 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.
