We have two cells E1 and E2 with internal resistance r1 and r2 connected in parallel with a resistor R.
Let, I1 and I2 be the current through E1 and E2 respectively.
By applying KCL(Kirchhoff's Current Law),
I = I1 + I2
Let their resultant EMF is Eeff
resultant resistance be Req.
By KVL(Kirchhoff's Voltage Law)
Potential across upper branch =
Potential across Lower Branch =
After solving we will get
