Question

In a closed circuit, the e.m.f. of a cell is always

• A. Less than potential difference
• B. More than potential difference
• C. Half of the potential difference
• D. Double of the potential difference

Answer 1

The correct option is B More than potential difference

In a closed circuit, emf of a cell is always more than the potential difference of the cell.

$V=E-Ir$ where $E=$emf, $V=$ potential difference across cell

and $r=$ internal resistance of cell

Answer-(B)
