An inductor and a resistor are in series with a sinewave voltage source. The frequency is set so that the inductive reactance is equal to the resistance. If the frequency is increased, then
options:
Voltage across the inductor= Source Voltage
Voltage across the inductor> Voltage across the resistor
Voltage across the inductor= Voltage across the resistor
Voltage across the resistor > Voltage across the inductor
