# 3 batteries in parallel

**1. The problem statement, all variables and given/known data**

two batteries A and B are connected in pareallel. A has emf of 108V and internal resistance of 3 Ω while B has emf of 120V and internal resistance of 2Ω. The battery terminal is connected to battery C in series with a 25 resistor. Battery C has emf of 30V and negligible internal resistance.

**2. Relevant equations**

find the value and direction of current in each battery and terminal voltage of B.

**3. The attempt at a solution**

I’m struggling to find the current in each battery first and I have tried to find the terminal voltage of B by using Kirchhoff’s law and nodes but cannot get the right answer.
