Question

The amount of charge given off by a usb charger is 160 coulombs and the time is taken is 80 seconds. How much current flows through the charger?

Answer 1

Given that the amount of charge is q = 160 C

The time taken is t = 80 s

We have to find the value of current.

The current can be calculated by the formula

`I\text{ =}(q)/(t)`

Substituting the values, the current will be

`\begin{gathered} I=(160)/(80) \\ =2\text{ A} \end{gathered}`

Thus, the 2 A current flows through the charger.
