Question

A current of 0.5 A is drawn by a filament of an electric bulb for 12
minutes. Find the amount of electric charge that flows through the circuit​

Answer 1

Explanation:

Given parameters

Current (I) = 0.5 A

Time = 12 minutes

Time in minutes can be converted into seconds as follows

Time (t) = 12 × 60 = 720 sec

Q = I × t

Q = 0.5 × 720

Q = 360 C

Answer 2

Given:

Current that is drawn by the filament of an electric bulb = 0.5 A

Time period for which the current flows = 12 minutes = 720 sec

To find:

The amount of electric charge that flows through the circuit.

Solution:

We know that the formula of electric charge is:

Q = I×t

Where I is the amount of current and t is the time period.

On substituting the values in the formula, we get:

Q = 0.5 × 720

Q = 360 C

Thus, the amount of electric charge that flows through the circuit will be 360 C.
