Question

If 1600 electrons passes through a point in 8 seconds then what is the current flowing through that point? Answer in Ampere.

Answer 1

Answer:

Given:

1600 electrons pass through a cross-section in 8 seconds.

To find:

Current flowing through that point.

Concept:

Current refers to rate of flow of charge. In other words , current is the ratio of charge to the time taken to flow through the cross-section of the conductor.

Calculation:

Charge of each electron = 1.6 × 10^(-19) C

Charge of 1600 electrons

= 2560 × 10^(-19) C

Now this amount of charge flowed in 8 seconds.

Therefore Current be I

$I = \dfrac{charge}{time}$

$= > I = \dfrac{2560 \times {10}^{ - 19} }{8}$

$= > I = 32 \times {10}^{ - 18} amp$

So final answer :

$\boxed{ \red{ \bold{ \huge{I = 32 \times {10}^{ - 18} amp}}}}$

We know that,

Charge of one electron = 1.6×10^¯19

Now, charge of 1600 electrons= 1.6×1600×10^¯19

=2, 560×10^¯19

This was done in 8 seconds.

Now, we need current in Ampere

Current = charge / Given time

=2,560×10^¯19/8

=320×10^¯19

=32×10^¯18 Ampere
