A sine wave voltage source is connected across a series combination of a resistor and an inductor.The frequency is set so that inductive reactance is equal to resistance.If the frequency is increased then

A sine wave voltage source is connected across a series combination of a resistor and an inductor.The frequency is set so that inductive reactance is equal to resistance.If the frequency is increased then

A.  Vr>Vl
B.  Vr<Vl
C.  Vl=Vr
D.  none of the above

Explanatory answer:

XL=2*pi*f*L

as f increases XL increases

so voltage drop across inductor, IXL increases but voltage drop across resistance remains same because resistance not depends on frequency.

The correct answer will be: Vr< Vl
