Question

write two differences between emf and p.d.​

Answer 1

Answer:

Potential Difference (Pd)

E.m.f is the energy supplied to the unit charge by the cell. Potential difference is the energy dissipated as the unit charge passes through the components. E.m.f is the cause. Potential difference is the effect.
