Question

The filament of
an electric bulb drawn a current
of 0.4A calculate the amount
of charge if bulb light for 2hours
​

Answer 1

Answer:

Given: Current or I= 0.4 A. Duration of the electric bulb lights = 3 hours.

To find: The amount of charge flowing through the circuit.

Charge is given by Q and is calculated by the formula: Time has to calculated in seconds, so we get. = 10800 sec. where,C is the Coulomb which is unit of charge.

Explanation:

Answer 2

Answer:

I=Q

__

T

0.4 = Q/10800

(t=3×3600=10800)

Q =10800×0.4=4320

so the charge is 4320 coulomb.
