Question

A total of 6 into 10 to the power 46 electrons flows through a current carrying conductor when connected to an external power apply for 20 second find the value of current in conductor

Answer 1

The value of current in tje conductor is 4.8 ×10 ^26

Answer 2

Given:

• Number of electrons = 6 × 10⁴⁶
• Time taken = 20 seconds.

To find:

• Current in the conductor?

Calculation:

Current is defined as the rate of flow of charge with respect to time.

• Let current be i :

$\therefore \: i = \dfrac{q}{t}$

• Now, total charge can be represented in terms of electrons charge as follows:

$\implies \: i = \dfrac{n \times e }{t}$

$\implies \: i = \dfrac{(6 \times {10}^{46} )\times (1.6 \times {10}^{ - 19} ) }{20}$

$\implies \: i = 0.48 \times {10}^{( - 19 + 46)}$

$\implies \: i = 0.48 \times {10}^{27} \: ampere$

So, the net current through the conductor is 0.48 × 10²⁷ ampere.
