Answer 2

Given,

The total current flowing through a car headlamp = 2A

Duration for which the headlamp is switched on = 40 minutes

To find,

Amount of charge that passes through the headlamp.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

Total current flowing

= (total amount of charges flowing)/(total time)

=> total amount of charges flowing = (total current flowing)×(total time){Equation-1}

Now, according to the question;

Amount of charge that passes through the headlamp

= (total current flowing)×(total time)

= 2 A × 40 mins

= 2 A × 40 mins × 60 seconds

{Since 1 min = 60 sec}

= 4800 Coulombs

Hence, the total amount of charge that passes through the headlamp is equal to 4800 Coulombs.
