Conductor resistance

Calculate the resistance value of the electrical conductor if it is connected to a voltage of 12 V and an electric current of 0.3 A passes through it.

Correct answer:

R =  40 Ω

Step-by-step explanation:

$$\begin{gathered} U=12\text{V} \\ I=0.3\text{A} \\ I=U/R \\ R=\frac{U}{I}=\frac{12}{0.3}=40\Omega \end{gathered}$$
