Problem 3: An inductor with L = 4.5 H is in a closed circuit with I = 0.85 A (see the diagram). When the switch is opened, the current goes to zero in Δt = 0.19 s.
Randomized Variables:
L = 4.5 H
I = 0.85 A
Δt = 0.19 s
Part (a) Express the magnitude of the average induced emf on the inductor, εave, in terms of L, I and Δt.
Part (b) Calculate the numerical value of εave in volts.
