|peak source voltage= (v1rms+v2rms)*1.414
= (7.5+4.2)*1.414 = 16.54

|If in the statement component connect in series then component value will be add on all time.|
|Siddu said: (Jan 31, 2012)|
|Here 7.5/.707 = 10.6
4.2/.707 = 5.800000
10.6 + 5.8 = 16.5

|Vrms = Vmax/1.414
Vmax = Vrms*1.414
= 16.54 Volt

|As this is AC Circuit, then how can we add two voltages algebraically. We have to do complex summation.|
|Pranjal said: (May 13, 2017)|
|Yes, you are correct. @HIT B.
We cannot add them directly as they are in AC circuit.
|Parth said: (Jun 23, 2017)|
|Hypothetically they are in phase.
As phase difference is not given.
Thus, their direct addition is possible.
|Ebenesar said: (Apr 7, 2018)|
|Rms value is equal to dc voltage so we can add.|

|Drop accross series resistor = 7.5+4.2 = 11.7Vrms.
Vrms = 0.707*Vp.
Vp = Vrms/0.707.
= 11.7/0.707 = 16.54V.
