Answer #1

An RL circuit with L = 23 mH has an emf of 12 V applied to it
starting at time t = 0. When t = 0.19 ms, the rate of change of
current in the circuit is 263 A/s. Determine the resistance.
Express your answer in ohms.

[Series circuit analogue: RLC circuit with nonzero resistance R
and nonzero voltage E(t) as forcing function is analogous to a
forced damped spring/mass system.] Consider the RLC circuit with
inductance L = 8 henrys, resistance R = 16 ohms, capacitance C =
0.025 farads, and voltage E(t) = 17 cos 2t volts.
(a) Find the current in the circuit for t > 0, given that at
time t = 0 the capacitor is uncharged and there is no current
flowing....

Here is a simple circuit consisting of a non-ideal battery, with
emf = 10, and two resistors, 5 ohms and 10 ohms. The fact that the
battery has an internal resistance will affect the potential
difference across the two resistors in the circuit. By what
percentage does the potential across the 10 ? resistor change due
to the internal resistance of the battery?

18-5 A self-inductance L, a resistance R, and a
battery of emf epsilon b are all connected in series. Use energy
considerations to show that the current i satisfies the
