Question

Obtain an expression for equivalent emf and equivalent internal resistance of two cells connected to parallel

Answer 1

Answer:

= I (R + r). ε = IR + Ir. V = ε – Ir. 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.May 13, 2018
