Question

a total of 6*10^46 electrons follow through a current carrying conductor when connected through external power supply for 20s find the value of current in the conductor​

Answer 1

Answer :-

Value of current in the conductor is 4.8 × 10²⁶ A .

Explanation :-

We have :-

→ Number of electrons = 6 × 10⁴⁶

→ Time taken = 20 s

→ Charge of an electron = 1.6 × 10⁻¹⁹ C

________________________________

Firstly, let's calculate the total charge carried by 6 × 10⁴⁶ electrons :-

⇒ Q = 6 × 10⁴⁶ × 1.6 × 10⁻¹⁹

⇒ Q = 9.6 × 10⁴⁶⁻¹⁹

⇒ Q = 9.6 × 10²⁷ C

________________________________

Now, we know that :-

I = Q/t

Substituting values, we get :-

⇒ I = 9.6 × 10²⁷/20

⇒ I = 0.48 × 10²⁷

⇒ I = 4.8 × 10²⁶ A

Answer 2

Answer:

Given :-

A total of 6 × 10⁴⁶;electrons follow through a current carrying conductor when connected through external power supply for 20s

To Find :-

Current

Solution :-

We know that

Charge = Charge of one electron × Number of electrons

Charge = 1.6 × 10-¹⁹ × 6 × 10⁴⁶

Charge = (1.6 × 6) × (10⁴⁶ - ¹⁹)

Charge = 9.26 × 10²⁷

Now

Current = Charge/Time

Current = 9.26 × 10²⁷/20

Current = 0.48 × 10²⁷ A
