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 VR ≥ VL VL > VR VL = VR VL < VR VR ≥ VL VL > VR VL = VR ANSWER DOWNLOAD EXAMIANS APP
Inductors The winding resistance of a coil can be increased by using a thinner wire changing the core material increasing the number of turns or using thinner wire increasing the number of turns using a thinner wire changing the core material increasing the number of turns or using thinner wire increasing the number of turns ANSWER DOWNLOAD EXAMIANS APP
