Question

$Derive an equation for effective internal resistance and effictive emf when two cells are connected in parallel$​

Answer 1

Answer:

Emf and Internal Resistance Equation:

The cell can be modified with an emf ε and the internal resistor with resistance r which is connected in series. ... So, V = ε – Ir, where V is the potential difference across the circuit, ε is the emf, I is the current flowing through the circuit, r is internal resistance.
