    Potential difference in junction of two cells one 4.5V and one 3V

    1. If two cells, one of 4.5V and one of 3V are connected in parallel what is the potential Difference across the junctions between them. 2. I = \frac{V}{R} 3. As 4.5v is greater it is the potential difference as they don't add up?
