Question

If 1 mili coulomb (mC)charge flows in a conductor for 2mili seconds (ms), then the current in the conductor will be

Answer 1

Given :

• Charges flowing through conductor, Q is 1 mili coulomb or 1 ^ -3 Coulomb

• Time period is 2 mili seconds or 2 ^-3 seconds

To find : Current in the conductor, I

Solution :

Current is defined as the rate of flow of changes.

That means, current = Number of changes ÷ Time period.

OR

>> I = Q/t

Substitute given values of changes and time period.

>> I = (1 mC )/(2 ms)

>> I = 1 ^( -3) / 2 ^( - 3 ) Ampere

>> I = 0.5 Ampere

Required current is 0.5 Ampere.
