Question

A steady current of 2.5A flows in a wire connected to a battery. But after 4.0
min, the current suddenly ceases because the wire is disconnected. How much
charge passed through the circuit? (Show your Solution )

Answer 1

The charge passed through the circuit is 600 C

Explanation:

Given:

A steady current of 2.5 A flows in a wire connected to a battery

After 4 minutes the current suddenly ceases

To find out:

The amount of charge passed through the circuit

Solution:

Given that

i = 2.5 A

t = 4 minutes = 240 seconds

We know that current is charge flowing per unit time

Thus,

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

or, $q=it$

Where q is the charge

Thus,

$q=2.5\times 240$

$\implies q=600$ C

Hope this answer is helpful.
