Homework Answers
(b) passes direct current and opposes time varying current.
Resistance of inductor -
XL = WL
W = Angular frequency
L = inductance
For DC current Angular frequency will be zero. So resistance will be zero. So inductor will pass DC current.
Will have resistance for time varying current.

To understand the units of inductance, the potential energy
stored in an inductor, and some of the consequences of having
inductance in a circuit.
After batteries, resistors, and capacitors, the most common
elements in circuits are inductors. Inductors usually look like
tightly wound coils of fine wire. Unlike capacitors, which produce
a physical break in the circuit between the capacitor plates, the
wire of an inductor provides an unbroken continuous path in which
current can flow. When the current in...

Tipler6 28.P.035. A current integrator measures the current as a function of time and integrates (adds) the current to find the total charge passing through it. (Because I = dq/dt, the integrator calculates the integral of the current or Q = ∫ I dt.) A circular coil that has 300 turns and a radius equal to 4.50 cm is connected to such an instrument. The total resistance of the circuit is 20.0 Ω The plane of the coil is originally...
