Question

Now the friends consider an AC circuit that includes an inductor and light bulb in series. Zoey asks Dominic to tell her, if the frequency of the AC source is changed and ΔVmax is held constant, when the bulb is the brightest. Which response is correct? "The brightness cannot be determined unless we also know the value of ΔVmax. ""The brightness is the same at all frequencies." "It glows brightest at high frequencies.""It glows brightest at low frequencies."

Step 1

Step 1: In a series circuit with a resistor (bulb) and an inductor, the total impedance is Z = sqrt(R^2 + (ωL)^2), where ω = 2πf. Show more…
