voltage across the parallel resistors are equal.... So votage Vs equals to the voltage across R3 resistor...

Polarity information is missing. So the ans may be -9v also.

Because voltage is same in parallel circuit and current is same in series circuit.

I3 = V3/R3 = 9V/1.8KOhm = 5mA.

V = I3R3 = 5*1.8 = 9V.

Therefore Vs = 9V.

In parallel circuit the voltage remains constant, so Vs is also 9v.

Voltage drop is equal in each branches. So v3 = vs = 9.

Mpavankumar said: (May 20, 2015)  
From the parallel connection same voltage in each branch that is why the answer is 9v.

Voltage divides in series and current in parallel.

Mukesh Kumar said: (Aug 15, 2016)  
Voltage across parallel combination is always same.

Krish said: (Sep 10, 2016)  
Voltage is parallel. V3 = 9. So Vs also 9 V.

Yogesh Girase said: (Mar 6, 2017)  
In parallel, the voltage is same.

Vs = V1 = V2 = V3.

Hello @Chaitu.

Ground means -ve know,
so, the answer is +9v.

In the parallel.

The Ckt voltage is same vs= v1=v2=v3=vn.
