Question

The wiring in a typical house can safely handle about 15 A of current. At this current level, how much charge flows through a wire in 1 hour?

Answer 1

Answer : The charge flows through a wire in 1 hour is,
`5.4* 10^4C`

Explanation :

Formula used :

`I=(q)/(t)`

where,

I = current = 15 A

q = charge = ?

t = time = 1 hour = 3600 s

Now put all the given value of in the above formula, we get:

`15A=(q)/(3600s)`

`q=15A* 3600s`

`q=54000C=5.4* 10^4C`

Therefore, the charge flows through a wire in 1 hour is,
`5.4* 10^4C`
