Question

in the circuit the potential difference across 3 volt and if the internal impedance of the cell is 1 ohm then the EMF of battery is ​

Answer 1

Answer:

It is equal to the potential difference across the terminals of the cell when no ... e = electromotive force in volts, V; E = energy in joules, J; Q = charge in coulombs, C. Batteries and cells have an internal resistance (r) which is measures in ohm's (W). When electricity flows round a circuit the internal resistance of the cell itself .
