Question
Two identical cells, each of emf E, having negligible internal resistance, are connected in parallel with each other across an external resistance R. What is the current through this resistance?
Solution
The cells are arranged as shown in the circuit diagram given below:
As the internal resistance is negligible, so total resistance of the circuit = R
Potential difference across the resistance = E
So, current through the resistance,`I=E/R`
