Question

Calculate the amount of charge that would flow in one hour through the element of an electric iron drawing a current of 0.4 amps.

Answer 1

Answer:

Im not sure whether this explanation is 100% right, so please check again with one of you colleagues.

Explanation:

Now, we know that current (I) is the rate of flow of charge.

(ie.) I = q/t (where q is charge and t is time in Coulomb and Seconds units respectively.)

Given: I = 0.4 ampere

t = 1 hour (convert into seconds) = 3600 seconds.

Substitute into the equation,

I = q/t

0.4 = q/3600

So, q = 3600 × 0.4

Therefore, q (charge) = 1440 Couloumbs.

(Please check the spelling of coulomb lol)

Hope this helped!

Answer 2

ANSWER:

1440 Coulombs

EXPLANATION :

I = Q/t

therefore Q = It

Here:

I = 0.4 A

t = 1 hr -> 3600 s

Q = 4/10 x 3600

Q = 1440 C

HOPE IT IS HELPFUL !!!!!!!!!!!!!
