Question

If a battery-operated car has a resistance of 3 Ohms and the current moving through it is 2 amps, what is the voltage of the battery?

A) 6V
B) 1.5 V
C) 1 V
D) 0.67 V

Answer 1

For me I think it is A

Step-by-step explanation:

Answer 2

A) 6V

Step-by-step explanation:

To solve this problem we need to use ohm's law

We have the resistance

`Resistance=R=3ohms`

and the current:

`Current=I=2A`

To find the voltage we use the following formula from ohm's law:

`Voltage=(Current)(Resistance)`

so

`V=I*R`

substituting the known values:

`V=(2A)(3ohms)=6volts`

the voltage of the battery is 6V which is option A.
