[A]. is 6 V
[B]. depends on the current flow
[C]. depends on the resistor values
[D]. is 30 V

Answer: Option D

Total volage drop = source voltage.

v=i1r1+i2r2+....i5r5
Vi=IiRi(voltage drop across each resistor )
i=1,2,3,....
V=V1+V2+V3+V4+V5
V=6+6+6+6+6=30V

@Kumar

Thanks for your explanation.

The series circuit voltage is different, current is same here each resistor has 6V hence the V=V1+V2+V3+V4+V5, {6+6+6+6+6=30V} the source voltage is 30 volts.

5 resistor having same voltage drop 6v means they are having a same resistance.

Therefor 5*6 = 30v.

Vs=-Vd.
hence Vs+Vd=0.
number of resistors=5.
voltage drop on one resistor=6V.
Total Voltage drop(Vd)=6*5=30.
Vs=-Vd.
so vs should be 30 to equalize the equation vs+Vd=0.

He is not given that they are equal voltage, then how it is 30v?

It depends on R or I value.

D.Jyothi said: (Aug 30, 2018)  
Here, it is no equal resistance. How does it say 30v?

If he gave they are equal resistance, then it becomes 30v, right?

Anybody solve this.

@D.Jyothi.

Series circuit means current same and here also given voltage drop that means resistor of all branches must be equal or same.
