A 12.0 V battery is in series with a switch, a 0.30 H inductor, and a 19 Ω resistor.
A). What's the time constant τ? I calculated τ to be 0.016 s or 16 ms which came back correct. It is the next part that I am having trouble with.
B). Find the potential differences across the inductor at t = τ.
C). Find the potential differences across the resistor at t = τ.
D). Find the potential differences across the inductor at t = 4τ.
E). Find the potential differences across the resistor at t = 4τ.
