Question

It takes 1 minute for 45 c to pass a point in a circuit, what is the current flowing through the circuit?

Answer 1

0.75 A

Step-by-step explanation:

An electric current is a flow of charged particles.

A current is defined through its intensity, which is given by:

`I=(q)/(t)`

where

I is the current intensity

q is the charge passing through a given point in the circuit

t is the time it takes for the charge q to pass that point in the circuit

In this problem, we have:

q = 45 C is the charge passing through the point in the circuit

`t=1 min = 60 s` is the time elapsed

Therefore, the current intensity is:

`I=(45)/(60)=0.75 A`
