Question

1. An electrical bulb drws a current of 1.25 A for 10 mins. Calculate the amount of electric charge that flows through the circuit?
Explain in detail​

Answer 1

Given:-

• Electric current is 1.25 A.
• Time is 10 mins.

To find:-

• Electric charge.

Explanation:-

Conversion:-

Time = 10 mins

1 minutes = 60 seconds

= 10 × 60

= 600

Time is 600 seconds.

We know,

$\boxed{ \red{ \bigstar \: \bf I = \dfrac{Q}{t} }}$

Where,

• I is electric current. SI unit of electric current is Ammeter or A.
• Q is electric charge. SI unit of electric charge is Coulomb or C.
• t is time. SI unit of time is Second or s.

Now,

$\implies \sf 1.25 = \dfrac{Q}{600}$

$\implies \sf 1.25 \times 600 = Q$

$\implies \purple{ \boxed{ \sf \bold{Q =750}} \star}$

Thus,

The amount of electric charge flows through the circuit is 750 C or coulombs.

Answer 2

Answer:

Given :-

• An electrical bulb draws a current of 1.25 A for 10 minutes.

To Find :-

• What is the amount of electrical charge that flows through the circuit.

Formula Used :-

✧ Q = I × t ✧

where,

• Q = Electrical charge
• I = Electrical current
• t = Time

Solution :-

Given :

• Electrical current = 1.25 A
• Time = 10 minutes = 10 × 60 = 600 seconds

According to the question by using the formula we get,

⇒ Q = 1.25 × 600

➠ Q = 750 C

∴ The amount of electrical charge that flows through the circuit is 750 C .
