A solenoid with a radius of 8.0 x 10-3 meter and 210 turn/cm is used as an inductor in a circuit. When the solenoid is connected to a source of 15 Volt rms at 22 kHz, an rms current of 3.1 x 10-2 Amp is measured. Suppose the resistance of the solenoid is negligible.
(a) Evaluate what is the inductive reactance?
Ω
(b) Evaluate what is the length of the solenoid?
cm
