has been closed for a long time interval and is opened
at t = 0. Also
assume R = 4.50 Ω, L = 1.14 H, and = 12.5 V.
Two adjacent rectangular loops, one to the left of the other,
form a circuit. The left side of the left loop contains a battery
of emf ℰ, for which the positive terminal is above
the negative terminal. The top side of the left loop contains a
resistor R, and the top side of the right loop
contains a resistor 2R. The right side of the right loop
contains an inductor L. The bottom side of the left
loop contains an open switch S. The right side of the left loop,
which is the left side of the right loop, contains another
resistor R.
(a) Before the switch is opened, does the inductor behave as an
open circuit, a short circuit, a resistor of some particular
resistance, or none of those choices?
an open circuita short circuit a
resistor of some particular resistancenone of these choices
(b) What current does the inductor carry?
mA
(c) How much energy is stored in the inductor
for t < 0?
mJ
(d) After the switch is opened, what happens to the energy
previously stored in the inductor?
(e) Sketch a graph of the current in the inductor
for t ≥ 0. Label the initial and final
values and the time constant.
