Question

Mention the condition in which charges can move in a conductor. Name the device used to maintain this condition in an electric corcuit

Answer 1

potential difference .

Electric cell or a battery .

Explanation:

Charges can move, if there is a difference of electric pressure or potential difference along the conducor. Electric cell or a battery ( consisting of o e or more cells) is a device used to maintain the condition in an electric circuit.

Answer 2

$\huge{ \underline{\boxed{\red{ \color{red}{\textsf {\textbf{An}{\color{blue}{\textbf {\textsf{sw}}{\color{green}{\textbf{\textsf{er}}}{\color{orange}{\textsf{\textbf{~:-}}}}}}}}}}}}}$

Charge can move in a conductor only when a potential difference is maintained between it's ends .

A cell or a battery is used to maintain potential difference and hence , there is a flow of electric charges in an electric circuit .
