heyy simple one yaar
just apply Kirchoff's law
suppose the 5 volt battery draw i current
then 5 - 5i - 10 = 0
therefore i = 1 amp. - ans..

Yes, current here = 3A. Use Superposition theorem.

@ akshay
you have wrongly applied the kirchoff's law.

I ALSO USED SUPERSOTION METHOD
VERY USEFUL

Using Nodal Analysis ->
Potential difference across 5ohm resistor = 10 - (-5) = 15 V
Hence, 15 = i * 5 or i = 3A

Superposition theorem is very simple. Basically you consider each of the voltage sources independently, removing the other source, and find the contribution of these sources across a circuit element, and then add the net result.
Example, in this problem: consider the 5 V battery first. It delivers a current of 1 A across the resistor. Now consider the 10 V battery. It delivers a current of 2 A across the resistor. So, the total current due to both the sources = 1+2 A = 3A. (Note that directions are important)

karthik u r missing something. in superposition theorem, when one voltage source is taken in action all other voltage sources r |
