Question

What is the current in a circuit if the charge passing each point is 20 coulomb in 40s​

Answer 1

Current in circuit

$current = \frac{charge}{time}$

Let c for current

$c = \frac{20}{40}$

$c = 0.5$

Current =0.5 A

Answer 2

Answer:

Explanation:

GIVEN HERE - 

                       Charge =Q= 20C

                       time = T= 40 sec

As we know that Current is the rate of flow of charge.

     or we can say   Charge (Q) = current (I) * time (T)

⇒ Q= I * T

⇒ I = Q/T

⇒ I = 20 / 40

⇒ I = 1/2 amp
