Inductors An inductor and a resistor are in series with a sine wave voltage source. The frequency is set so that the inductive reactance is equal to the resistance. If the frequency is increased, then VL > VR VL < VR VR ≥ VL VL = VR VL > VR VL < VR VR ≥ VL VL = VR ANSWER DOWNLOAD EXAMIANS APP
Inductors A sine wave voltage is applied across an inductor. When the frequency of the voltage is decreased, the current is decreased is increased does not change momentarily goes to zero is decreased is increased does not change momentarily goes to zero ANSWER DOWNLOAD EXAMIANS APP
