Step 1
Step 1: The current through an inductor in an RL circuit is given by: $I(t) = I_0 e^{-t/\tau}$ where $I_0$ is the initial current, t is the time, and $\tau$ is the time constant given by $\tau = L/R$. Show more…

For the given circuit, the switch is closed for a long time and then opened at t=0. R1 = 0.5 kΩ, R2 = 110 Ω, L = 9 H, V = 7 V, and V = 18 Volts are given. Calculate the inductor current at t = 12 seconds. IL(t=1.2) = ? (Your result must be in mA) Only give numeric results. (If you found 9 mA, write down 2)

To practice Problem-Solving Strategy 30.1: Inductors in Circuits. A circuit has a 2.7 V battery connected in series with a switch. When the switch is closed, the battery powers two paths in parallel, one of which has a resistor of resistance R1 = 90 ̐ in series with an inductor of inductance L = 1.5 10⁻² H, while the other has a resistor of resistance R2 = 430 ̐. What is the current supplied by the battery at a time t = 0.25 ms after the switch is closed? EXECUTE the solution as follows Part C What is the current i1 supplied by the battery a time t = 0.25 ms after the switch is closed? Express your answer in amperes to three significant figures. i1 = 6.44 · 10⁻³ A
