Question

1 A current of 0.5A is drawn by
la tilament of an electric bulb
tor 15 minutes. Find the amount
of electric charge that
that flows
through h the circuit. [q = 1350 c]​

Answer 1

Answer:-

• 450 c is the required answer .

Given:-

• Current ,I = 0.5A
• Time taken ,t = 15min = 15×60 = 900s

To Find:-

• Amount of charge ,q

Solution:-

According to the Question

It is given that current of 0.5A is drawn by filament of an electric bulb for 15 minutes.

we have to calculate the amount of charge that flow through the circuit.

As we know that Current is defined as the amount of charge flowing per unit time.

• I = q/t

where,

• I denote Current
• q denote charge
• t denote time taken

Substitute the value we get

$\longrightarrow$ 0.5 = q/900

$\longrightarrow$ 0.5 × 900 = q

$\longrightarrow$ q = 0.5×900

$\longrightarrow$ q = 450 C

• Hence, the amount of charge flows is 450 Columbus .

Answer 2

Given :-

A  current of 0.5A is drawn by  filament of an electric bulb  tor 15 minutes.

To Find :-

Amount of electric charge

Solution :-

We know that

Charge = Current × Time

1 min = 60 sec

15 min = 15 × 60 = 900 sec

Now

Charge = 0.5 × 900

Charge = 450 C

Hence

Charge is 450 Coulomb
