Diode forward resistance

What is the value of the resistance of the rectifier diode in the forward direction if the current IF = 5 A flows through it and the voltage between the anode UF = 820 mV?

Final Answer:

R =  0.164 Ω

Step-by-step explanation:

$$\begin{gathered} I=5\text{A} \\ U=820/1000=\frac{41}{50}=0.82\text{V} \\ I=\frac{U}{R} \\ R=\frac{U}{I}=\frac{0.82}{5}=0.164\Omega \end{gathered}$$
