How do the currents produced by a 1.5 v flashlight battery and a 12 v car battery compare if the resistance is the same?

Current offered by the car battery is 8 times the current offered by the batteries in the flash lights.

I' = 8 × I

Explanation:

Voltage used in flash lights ,V = 1.5 Volts

Current offered by the V = I

...(1)

Voltage used in car battery,V' = 12 Volts

Current offered by the V' = I'

..(2)

Dividing (2) and (1)

(Given that resistance offered by both is same,R'=R)

I' = 8 × I

Current offered by the car battery is 8 times the current offered by the batteries in the flash lights.
