Question

A toy car has a 1. 5 A current, and its resistance is 2 Ω. How much voltage does the car require? V.

Answer 1

Answer: Voltage = (current) x (resistance)

Voltage = (1.5 A) x (2 ohms)

In order to MAKE 1.5 A of current flow through the toy car, you have to PROVIDE 3 volts from the battery.
