hope so it help you

Answer 2

Answer:

1.Electric current: It is a closed conducting path through which electric current flows.

2.Unit of current:Unit of current is 1 Ampere. It means flow of 1 columb per second.

3. Since theta = xe

so x = theta/e

x = 1/1.6×10^-19

x = 1×10^19/1.6

x = 1×10^19/16×10^-1

x = 1×10^20/16

x = 0.0625×10^20 = 6.25×10^18
