Resistance 80700

Determine the largest voltage on a resistor with a resistance of 150 ohms if the largest permitted electrical power current in the resistor is 2 W.

Correct answer:

U =  17.3205 V

Step-by-step explanation:

$$\begin{gathered} R=150\Omega \\ P=2\text{W} \\ P=U^2/R \\ U=\sqrt{P\cdot R}=\sqrt{2\cdot 150}=10\sqrt{3}=17.3205\text{V} \end{gathered}$$
