Question

why the terminal potential difference of a cell is always less than its e.m.f?​

Answer 1

Answer:

when the current flows through the circuit, there is fall of potential across the internal resistance of the cell. the potential difference between the two poles of the cell is less than the e.m.f. of the cell by an amount equal to potential drop across the internal resistance. therefore, the terminal potential difference of a cell is always less than its e.m.f.

Answer 2

Answer:

when the current flows through the circuit, there is fall of potential across the internal resistance of the cell. the potential difference between the two poles of the cell is less than the e.m.f. of the cell by an amount equal to potential drop across the internal resistance. therefore, the terminal potential difference of a cell is always less than its e.m.f.
