how to find the applied voltage?

charmcaster.engg · Jan 19, 2015

In a 20 Vac series RC circuit, if 20 V is measured across the resistor and 40 V is measured across the capacitor, the applied voltage is?

RC series. Therefore I calculated it as 20V+40V=60V. But the answer is 45V.

show us your calculations and we can see where you may have gone wrong

You'll have to take into account the phase shift, see your other threads.

I tried but I did not get it. Can you give me the formula?
