Question

6.25 x10^18 electrons are passing in time interval of 2 seconds through a conductor. Find the current flowing through it

Answer 1

Answer:

current flowing will be 0.5 Ampere

Answer 2

Given:

6.25 x10^18 electrons are passing in time interval of 2 seconds through a conductor.

To find:

Find the current flowing through it

Solution:

From given, we have,

6.25 x10^18 electrons are passing in the time interval of 2 seconds through a conductor.

The current is the rate of flow of charges.

The formula for calculating the amount of current, given the charge and time is,

I = Q/t

where, Q = ne

n is the number of charges

Therefore, we have,

I = Q/t = ne/t

I = (6.25 × 10^18 × 1.6 × 10^{-19}) / 2

I = 10 × 10^{-1} / 2

I = 0.5 A

Therefore, the current flowing through the conductor is 0.5 A.
