Vedclass · Answer

(A) In the circuit, the diode is in parallel with the resistance $R$. For $V For $V > 0$ (forward bias), the diode conducts after the knee voltage. Before the knee voltage, the current flows through the resistor. After the knee voltage, the diode offers very low resistance, so the total current increases rapidly. Combining these, the graph shows a linear relationship for $V  0$. Option $A$ correctly represents this behavior.

$A$ diode is connected in parallel with a resistance $R$ as shown in the figure. The most probable current $(I)$ - voltage $(V)$ characteristic is:
