Question

How much charge must flow past a point in 2.39s to produce a current of 7.26A?3.04C4.87C17.4C0.329C

Answer 1

Given:

the current is

$i=7.26\text{ A}$

The time is

$t=2.39\text{ s}$

Required: how much charge must flow during this time?

Explanation:

we know that,

current is given by

$i=\frac{q}{t}$

here, q is the charge and t is the time.

Plugging all the values in the above relation, we get:

$\begin{gathered} 7.26\text{ A }=\frac{q}{2.39\text{ s}} \\ q=7.26\text{ A}\times2.39\text{ s} \\ q=17.35 \\ q\approx17.4\text{ C} \\ \end{gathered}$

Thus, the charge must flow past a point in 2.39 s is 17.4 C.
