Chapter 4: Q18DQ (page 841)

8 Eight flashlight batteries in series have an emf of about 12 V, similar to that of a car battery. Could they be used to start a car with a dead battery? Why or why not?

Short Answer

Expert verified

No, 8 flashlight batteries in series could not be used to start a car with deadbatteries.

A car battery may have a current up to 250 amps or even larger.

The flashlight battery only provides about 0.30 amps.

Even if 8 batteries are connected in series, they are not enough to start a car dead battery

Step by step solution

01

Definition of battery

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices.

02

Compare a car battery with a flashlight battery

A car battery may have a current up to 250 amps or even larger.

The flashlight battery only provides about 0.30 amps.

Even if 8 batteries are connected in series, they are not enough to start a car dead battery.
