31. Alternating Current Inductors in AC Circuits
5PRACTICE PROBLEM
An AC power source with a variable angular frequency (ω) is connected to an R-L combination, as shown in the figure. Determine the expression of i) the current (I) in the circuit, ii) the voltage across the resistor, and iii) the voltage across the inductor as a function of ω. Hint: Use a phasor diagram.
