Question

A current of 25 m A is drawn by filament of an electric bulb for 10 minutes. Find the
amount of electric charge that flows through the circuit.​

Answer 1

Given :-

Current drawn by filament of an electric bulb = 25 A

Time taken by the electric bulb = 10 m

To Find :-

The amount of electric charge that flows through the circuit.​

Analysis :-

Here we are given with the current and time taken by the electric bulb.

In order to find the charge flown substitute the values given in the question such that charge flown is equal to current multiplied by the time.

Solution :-

We know that,

• i = Current
• q = Charge
• t = Time

Using the formula,

$\underline{\boxed{\sf Charge=Current \times Time}}$

Given that,

Current (i) = 25 A

Time (t) = 10 min = 600 sec

Substituting their values,

⇒ q = i × t

⇒ q = 25 × 600

⇒ q = 15000 C

⇒ q = 1.5 × 10⁴

Therefore, the amount of electric charge that flows through the circuit is 1.5 × 10⁴.

Answer 2

Answer:

Given :-

• Current = 25 Ampere
• Time taken = 10 min

To Find :-

Amount of electric charge

Solution :-

As we know that Charge is the product of Time and current

$\huge \bf \: Q = I \times T$

Here,

Q = Charge

I = Current

T = Time taken

10 min = 10 × 60 = 600 sec

$\sf \pink {Q = 25 \times 600}$

$\sf \red {Q = 15000}$

$\huge \bf \green{Q = 1.5 \times 10 {}^{4}}$
