The switch in the figure is closed at t = 0 when the current I is zero. When I = 37 mA, what is the potential difference across the inductor?
A circuit consists of a battery with E=50.0 V, two resistors R1=30.0Q, R2=15.02, and
an inductor L=0.3 H as shown in the figure. The switch S is closed at time t=0.
(a) Find the potential difference V.-V, just after the switch is closed.
(b) Find the currents i, and iz going through R, and R, and their directions, just after
the switch is closed.
(c) The switch is left closed a long time; find the currents i, and iz.
(d) After the switch is left closed a long time, it is opened again. Find V.-V, and
V.-Va just after the switch is opened.
In the figure, the battery is ideal and &= 12 V, R1 = 15 Q, R2= 25 Q, and L= 5.0 H.
Switch S is closed at time t= 0. (a) Just after the switch is closed, what are i1, i2, the potential
difference V2 across resistor 2, and the potential difference Vi across the inductor? (b) A long
time after the switch was closed, what are i1, i2, V2, and VL?
Then the switch S is reopened at t' = 0. (c) Just after the switch is opened, what are what are
i1, i2, V2, and VL? (d) What is the time constant of the circuit? (e) How long will it take until
the energy stored in the solenoid drops to half of its initial value at t'= 0?
