Question

In an electrical field, the resistance is 2 Ω and the current is 4 A. What is the voltage

Answer 1

To solve the problem, we can use Ohm's law, which states that

`V=IR`
where
V is the voltage
I is the intensity of current
R is the resistance

Using the data of our problem, I=4 A and
`R= 2 \Omega`, we find the voltage:

`V=IR=(4 A)(2 \Omega)=8 V`
