Calculate the reactance of a 120.0 mH long coil of wire connected to a 350.0 Hz AC power supply.
Determine the frequency of the emf applied to the inductor if the following graphs illustrate the voltage and current for the inductor.
In an inductor circuit, the peak current through an inductor is initially measured as 20 mA. Determine the new peak current if the peak value of emf voltage is halved.
Determine the voltage across the 10 Ω resistor shown in the electrical circuit for the following cases: i) Very low frequency, ii) very high frequency. Hint: Use a phasor diagram.
An ideal solenoid is connected to an AC power supply providing an alternating voltage of 9.0 V r.m.s. at a frequency of 12000 Hz. The peak current measured is 35 mA. Calculate the inductance of the solenoid.
