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:
$V=IR=(4 A)(2 \Omega)=8 V$
