Question

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 differential equation L (di/dt) + Ri = epsilon b. Now assume that i tidak sama dengan 0 and the battery is switced out of the circuit. Solve the resulting equation and find the relaxation time of this system.

Answer #1

Consider a series circuit with a resistor with resistance R, an
inductor with inductance L and an ac generator with angular
frequency, ω and peak voltage V0. Using Kirchoff’s laws, write and
solve the differential equation for the current, I.

For a resistance-inductance circuit. kirchoff's law leads to L
dI(t)/dt +RI(t)=V(t). Find I(t)?

A coil of L Henry of inductance and R Ohms of resistance in
series is put in series with a capacitor of C Farad of
capacitance.

Show that the energy WL + WC = constant.
Rate this constant.

A conducting bar of length L and resistance R is free to slide
on frictionless conducting rails of negligible resistance. The
circuit is immersed in a uniform and steady magnetic field of
strength B. Initially the bar is at rest and the switch is open.
The switch is closed. The battery provides a steady voltage V.

switch is closed?
b) What is the magnitude of the current at...

A solenoid with inductance L = 2.0 H is connected in series with
a resistor R = 10 ohms, as well as an AC power supply that is
providing current I(t) = I0 * cos( 2π * f * t ). The
current has an amplitude of 2 A and a frequency of 60 Hz.

Consider a simple series RLC circuit with the following values
for the resistance, inductance, and capacitance: R = 110 Ω
(ohms), L = 1 H (henries), and C = 0.001 F
(farads). Furthermore, a battery provides an external voltage,
e(t), into the circuit equal to 7 However, this
external voltage e(t) is not always flowing into
the circuit. Initially, the switch for the circuit is open and
there is no charge or current flowing through the circuit. At time
t...
