For series RC circuit, the formula is E= √(E resistive component^2 + E capacitive component^2)
E= √(20^2 + 40^2) = 44.72 V approx. 45 V.
The formula is from power triangle.
E= √(20^2 + 40^2) = 44.72 V approx. 45 V.

But the impedance of capacitor is counted as 1/jwc.

In A.C circuits Z = R+jX. So V = IZ.
So V = IR+jIX which in vector form so finally magnitude form is V = square root of V, VC.
So V = IR+jIX which in vector form so finally magnitude form is V = square root of V, VC.

I didn't understand the solution can anybody solve little more simple.
