Question

A current of 0.4 A is made to pass through an electric circuit
for 15 minutes. Find the amount of electrie charge that
flows through the cireuit.​

Answer 1

$\huge{\underline{\underline{\red{\bf{Given:}}}}}$

• A current of 0.4 A passes through an electric circuit.
• The charge flows for 15 minutes.

$\rule{200}4$

$\huge{\underline{\underline{\red{\bf{To\: Find:}}}}}$

• The amount of electric charge.

$\rule{200}4$

$\huge{\underline{\underline{\red{\bf{Answer:}}}}}$

Given that a charge of 0.4 A passes through an conductor for 15 minutes.

So , we know electric current as the rate of flow of electric charge is called electric current.

In mathematical form ,

$\large{\underline{\boxed{\purple{\bf{\leadsto Current=\dfrac{Charge}{time}}}}}}$

⇒0.4 A = q / 15 min.

⇒4/10 A = q / 15×60s .

⇒q = 4×15×60/10 C

⇒q = 360 C .

Hence the amount of electric charge is 360C .

Answer 2

Answer:

Charge passing through the conductor is 360 C.

Explanation:

I = 0.4 A

t = 15 min = 15 * 60 s = 900 s

Q = I * t

=> Q = 0.4 * 900

=> Q = 360 C.

So,

Charge passing through the conductor is 360 C.
