Question

iii) When in a conductor 400 coulomb charge flows in 20 seconds, then amount of current flow through conductor is​

Answer 1

Required Answer:-

Amount of current flowing is given by amount of change flowing through the conductor in unit time.

Here:

• Charge flowing = 400 C
• Time taken = 20 s

Then,

Current flowing will be:

$\large{ \boxed{ \boxed{ \rm{I = \frac{Q}{t}}}}}$

Plugging the values,

I = 400 C / 20 s

I = 20 C/s

I = 20 A (Ans)

Note:-

C/s is also known as Ampere (A), the SI unit of charge because Coulombs and Seconds is the SI unit of charge and time respectively.

Answer 2

Answer:

Given :-

• Charge = 400 coulomb
• Time = 20 second

To Find :-

Current

Solution :-

We know that

Q = TI

I = Q/T

I = current = ?

Q = Charge = 400

T = time = 20 second

I = 400/20

I = 40/2

I = 20/1

I = 20 ampere
