You want the current amplitude through a 0.450 mH inductor (part of the circuitry for a radio receiver) to be 1.50 mA when a sinusoidal voltage with an amplitude of 13.0 V is applied across the inductor. What frequency is required?

Explanation:

The formula for calculating the voltage across an inductor is expressed as

Given parameters

current amplitude I = 1.50mA = 1.5*10⁻³A

inductance L = 0.450mH = 0.450*10⁻³H

Voltage across the inductor = 13.0V

Required

frequency f

Substituting the given parametres into the formula, we have;

Hence, the frequency required is 3.067MHz
