Question

calculate the amount of charge that would flow in 2 hours through an element of an electric bulb drawing a current of 2.5 A​

Answer 1

Answer:

Given :-

• A current flow in 2 hours through an element of an electric bulb drawing a current of 2.5 A.

To Find :-

• What is the amount of charge.

Formula Used :-

$\clubsuit$ Charge Formula :

$\longrightarrow \sf\boxed{\bold{\pink{Charge =\: Current \times Time}}}$

where,

• Charge in Coulomb (C)
• Current in Ampere (A)
• Time in Seconds (s)

Solution :-

First, we have to convert time into seconds :-

$\leadsto \sf Time =\: 2\: hours$

$\leadsto \sf Time =\: 2 \times 60 \times 60$

$\leadsto \sf Time =\: 2 \times 3600$

$\leadsto \sf\bold{\purple{Time =\: 7200\: seconds}}$

Now, we have to find the amount of charge :-

Given :

• Current = 2.5 Ampere
• Time = 7200 seconds

According to the question by using the formula we get,

$\implies \sf Charge =\: 2.5 \times 7200$

$\implies \sf\bold{\red{Charge =\: 18000\: C}}$

$\therefore$ The amount of charge flows through an element of an electric bulb is 18000 Coulomb .
