Question

A current of $2\text{A}$ is flowing through a wire. The charge that would flow through the wire in $20\text{s}$ will be

​​​​​​​$[$0.77 Mark$]$

• A. $2\text{C}$
• B. $20\text{C}$
• C. $40\text{C}$
• D. $8\text{C}$

Answer 1

The correct option is C $40\text{C}$

Current is defined as the amount of charge flowing per unit time,

$i.e.i=\frac{Q}{t}$

$\Rightarrow Q=it$

$\Rightarrow Q=2\times 20$

$\Rightarrow Q=40\text{C}$
