A V = 84-V source is connected in series with an R = 1.1-kΩ
resistor and an L = 34-H inductor and the current is allowed to
reach maximum. At time t = 0 a switch is thrown that disconnects
the voltage source, but leaves the resistor and the inductor
connected in their own circuit.
a) How much time, in milliseconds, is needed for the current in
the circuit to drop to 9 % of its value at t =...

A series RL circuit consists of a 6.3 volt battery, a 175 ohm
resistor and an inductor.
(a) If the battery has been connected for a long time interval,
what is the current in the circuit?
(b) The battery is then removed from the circuit, so only the
resistor and the inductor are connected in series. What is the
inductance of the inductor if the current drops to half of its peak
value in 2.00 ms?
(c) The current is...

Madelyn and Scarlett decide to work a problem from the book. An
RLC circuit has been set up as illustrated in the simulation.
Initially, the switch S is at a, allowing the capacitor to charge.
With the capacitor already fully charged, the switch is moved to b
at time t = 0. As a result, the capacitor is being allowed to
discharge through the resistor and the inductor. Find the frequency
f of the oscillations in current that result, using...

, switch S1 is closed while switch S2 is kept open. The
inductance is L = 0.160 H , and the resistance is R = 120 Ω .
When the current has reached its final value, the energy stored
in the inductor is 0.300 J . What is the emf E of the battery?
After the current has reached its final value, S1 is opened and
S2 is closed. How much time does it take for the energy stored in...

A circuit is constructed with an AC generator, a resistor,
capacitor and inductor as shown. The generator voltage varies in
time as ε = Va - Vb = εmsinωt, where εm = 24 V and ω = 199
radians/second. At this frequency, the circuit is in resonance with
the maximum value of the current Imax = 0.63 A. The capacitance C =
180μF. The values for the resistance R and the inductance L are
unknown.
a) What is L, the...
