Question

An electric current of 5 amperes flows through a conductor for 15 seconds. Find the amount of charge that flows.

Answer 1

Step 1: Given data

Electric current, $I=5A$

Time, $T=15s$

Charge, $Q=?$

Step 2: Formula used

$I=\frac{Q}{T}$ ……………………….(a)

Step 3: Calculation of charge flowing through the conductor

Substituting the given values in equation (a), we get

$5A=\frac{Q}{15s}$

$Q=5A\times 15s$

$Q=75C$

$$Hence, the amount of charge flowing through the conductor is equal to $75C$.
