Let us for suppose that an i current is flowed in to the circuit such that "the voltage developed across the series pair of resistance and capacitor is == I(R+jXc)
The voltage = IR + j(IXc) = voltage acc resistance + j(voltage acrosscapacitor)
= 20+j40
= sqrt(20*20 + 40 *40)
= 44.72
The voltage = IR + j(IXc) = voltage acc resistance + j(voltage acrosscapacitor)
= 20+j40
= sqrt(20*20 + 40 *40)
= 44.72

Here, rc series circuit therefore as formula vt= squareroot of vr*vr+vc*vc=400.
1600=44. 72=45v.
Thats the answer.
1600=44. 72=45v.
Thats the answer.
