Question

Calculate the current flowing if a charge of 36 kilocoulombs flows in 1 hour.

Answer 1

Given:-

• Charge=36 Kilo coulomb

• Time=1 hour

To find:-

• Current flowing through the conductor

Solution:-

As we know that current flowing through the conductor can be said to 1 Ampere when 1 Coluomb or charge flows in 1 second.

It means that value of charge and time should be in standard form, but in the Question we have given charges and time in kilo coulomb and hour respectively. So let's convert them in standard units!

  1 kilo coulomb = 100 coulomb

36 Kilo coulomb = 36×1000

36 Kilo coulomb =36000 coulomb

Now,

1 hour=60 min

1 min=60 seconds

So,

1 min=60×60 seconds

1 min=3600 seconds

Now applying formula for current:

⇒ Current, I=Q/t

⇒ Current, I=36000 coulomb/3600 second

⇒ Current, I=10 coulomb/second

⇒ Current=1 Ampere

So the required value of current is 1 Ampere.
