Question

A car battery has a rating of 290 ampere-hours. This rating is one indication of the total charge that the battery can provide to a circuit before failing. (a) What is the total charge (in coulombs) that this battery can provide

Answer 1

Answer:

The total charge that can be delivered is 1044000 Coulombs

Explanation:

As we know that current I flowing given by:

I=Δq/Δt

Where Δq is charge moving

Δt is time

So

Δq=IΔt

Δq=290A×1 hour

Δq=290A×3600s

Δq=1044000 Coulombs

The total charge that can be delivered is 1044000 Coulombs
