The dynamic resistance of Si diode at room temperature when it conducts a forward current of 2 mA is ___? (V_T = 25 mV)

Transformer utilization factor (TUF) for the rectifiers is

The 6V Zener diode shown in the figure has zero Zener resistance and a knee current of 5 mA . The minimum value of R so that the voltage across it does not fall below 6V is _ Ω.

The reverse saturation current of a reverse biased p-n junction diode increases 64 times due to a rise in ambient temperature. If the original temperature was 50^oC, what is the final temperature?

Determine V_x and I_y assuming all are ideal diodes.

Determine the condition for the input voltage V_S such that diode D₁ and D₂ will be ON state. (Assume each diode has cut-in voltage, V_γ = 0.7 V).
