Question

charge 20C passes through a cross section of a conductor in 2sec. The current produced is ____ Ampere, *

Your answer


​

Answer 1

Given :

➳ Magnitude of charge flow = 20C

➳ Time interval = 2C

To Find :

⟶ Current flow in conductor

SoluTion :

➢ Current is defined as the rate of charge flow per unit time.

➢ It is a scalar quantity having only magnitude.

➢ Mathematically, I = Q / t

• I denotes current
• Q denotes charge
• t denotes time

➢ It is a fundamental quantity.

➢ SI unit : C/s or A

⇒ I = Q / t

⇒ I = 20/2

⇒ I = 10A
