Resistor current calculation

At a voltage of 16 V between the ends of the resistor, a current of 200 mA flows through the resistor. What current will flow through the resistor when connected to 48 V?

Final Answer:

I₂ =  600 mA

Step-by-step explanation:

$$\begin{gathered} I_1=200\text{mA} \\ {U}_2=48\text{V} \\ {U}_1=16\text{V} \\ {I}_2=\frac{U_2}{U_1}\cdot I_1=\frac{48}{16}\cdot 200=\frac{48\cdot 200}{16}=\frac{9600}{16}=600\text{mA} \end{gathered}$$
