Measurement 12251

The measurement showed that a current of 160 mA flows through the appliance at a voltage of 4 V. What current flows through this appliance when connected to a voltage of 12 V?

Correct answer:

I₂ =  480 mA

Step-by-step explanation:

$$\begin{gathered} I_1=160\text{mA} \\ {U}_2=12\text{V} \\ {U}_1=4\text{V} \\ {I}_2=\frac{U_2}{U_1}\cdot I_1=\frac{12}{4}\cdot 160=\frac{12\cdot 160}{4}=\frac{1920}{4}=480\text{mA} \end{gathered}$$
