Question

derive ab expression for equivalent emf when two cells are connected in series​

Answer 1

Answer:

Derive the expression for equivalent EMF and equivalent internal resistance when two cells are connected in series

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.

Answer 2

Answer:

Derive the expression for equivalent EMF and equivalent internal resistance when two cells are connected in series

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.
