Question

An electron gun emits 2.0 ×1016 electrons per second. What electric current does this correspond to?

Answer 1

Answer:

4 mili ampere.

Explanation:

The Electric current is flow of charge per unit time

The Electronic Charge is 1 6 × 10 to the power minus 19.

The electron gun emits 2 × 10 to the power 16 electrons

per second.

Thus in one second flow of charge from the Electronic

gun is :

2× 10^ -19 × 2 × 10^16b= 4 × 10^ - 3 = 4/1000 Amp

= 4 mili ampere.

Ans 4 mili ampere.

Answer 2

Electric Current corresponds to $3.2 \times 10^{-3} \mathrm{Amp}$.

Explanation:

An electron gun is nothing but an electrical component.

It is seen in some vacuum tubes that creates a collimated, narrow electron beam with a detailed kinetic energy.  

Step 1:

From the given statement,

No. of electrons flowing per second $=2 \times 1016 electrons / sec$

Charge passing in capacitor per second = $2 \times 1016 \times 1.6 \times 10^{-9}$.  

It is known that the current, I is equal to the flow of charge’s rate.

Electric current (i) = Vt

Current = $3.2 \times 10^{-3} \mathrm{Amp}$
