what is the formula for different resistors connected in parallel attached with emf like mixed grouping then what is the current in

it

Hiii Neha, You can solve it by using , Thevenin theorem, You can just short circuit all the voltge source and find equivalent resistance of the network. That wil be the Thevenin resistance . That will be the equivalent resistance seen by the network.

If you want to find out current then  Use the formula V=IR for each resistance and voltage across it, and add them all, you will get the desired current.

Hope this help.
