A capacitor and a resistor are connected in series to a sine wave generator. The frequency is set so that the capacitive reactance is equal to the resistance and, thus, an equal amount of voltage appears across each component. If the frequency is increased

Vc=i.Xc & Vr=i.R.
Given that
As given in question Vc = Vr
So f is inversely proportional to Vc.
Vr>Vc.

We know that Vc=i.Xc & Vr=i.R
Given that
Vc = Vr
So f is inversely proportional to Vc.
Vr>Vc
Given that
Vc = Vr
So f is inversely proportional to Vc.
Vr>Vc

xc=1/2pi.f.c;
So if f increases then xc decreases. So voltage drop across the 'C' decreases.
So if f increases then xc decreases. So voltage drop across the 'C' decreases.

As we know fc=1/2pifc. So if frequency increases than vc will decrease.

vc = i.xc and vr = i.r.
vc = vr.
So vr >vc.
vc = vr.
So vr >vc.
