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 VL < VR VR ≥ VL VL > VR VL = VR VL < VR VR ≥ VL ANSWER DOWNLOAD EXAMIANS APP

Inductors Five inductors are connected in series. The lowest value is 8 μH. If the value of each inductor is twice that of the preceding one, and if the inductors are connected in order of ascending values, the total inductance is 32 μH 8 H 64 μH 248 μH 32 μH 8 H 64 μH 248 μH 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 increased is decreased does not change momentarily goes to zero is increased is decreased does not change momentarily goes to zero ANSWER DOWNLOAD EXAMIANS APP
