Question

An electric current of 3A flows through a circuit for 20 minutes. What is the amount of charges flowing? *

Answer 1

Answer:

I=q/t

t=20*60=1200sec

q=I*t

q=3*1200

q=3600c

Explanation:

Answer 2

Given:

current (i) = 3A

time (t) = 20 minutes

To find:

Amount of charge (q)

Solution:

As we know,

Charge is the product of current and time.

q = i × t

here,

q is the charge,

i is the current flowing,

and t is the time.

Now, in our question time (t) is 20 minutes which is 1200secs.

Now, putting the values in above equation we get,

q = 3 × 1200

= 3600 columb

Hence, the amount of charge (q) flowing through the conductor is 3600 columb
