Determine the current in the light bulb if an electric charge of 300 C passes through its filament in 10 minutes.

The current in a light bulb can be calculated using the following formula:

I = q / t, where q is the magnitude of the electric charge that passed through the filament (q = 300 C), t is the time the charge passes through the filament (t = 10 min = 10 * 60 s = 600 s).

Let’s calculate:

I = q / t = 300/600 = 0.5 A.

Answer: In a light bulb, the current strength is 0.5 A.
