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

Answer:

A) 6V

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.

Answer 2

Answer:

For me I think it is A
