Question

if a current of 2 ampere is drawn for one hour through the filament of a bulb find the amount of charge flowing through the circuit​

Answer 1

Answer:-

• Current=I=2A
• Time=1hour=3600s
• Charge=Q=?

We know that.

$\boxed{\sf I=\dfrac{Q}{t}}$

$\\ \sf\longmapsto Q=It$

$\\ \sf\longmapsto Q=2\times 3600$

$\\ \sf\longmapsto Q=7200C$

Note:-

SI unit of charge is Coulomb (C)

Answer 2

Answer :-

Amount of charge flowing through the circuit is 7200 Coulombs .

Explanation :-

We have :-

→ Current = 2 A

→ Time = 1 hour

________________________________

Firstly, let's convert the time taken from hour to sec .

⇒ 1 hour = (60 × 60) sec

⇒ 3600 sec

________________________________

Now, we know that

Q = It

Where :-

• Q is charge .

• I is current .

• t is time .

⇒ Q = 2 × 3600

⇒ Q = 7200 C
