5V 3000 1000 . 2m 1 Si 4000 500 12V The circuit shown in Figure 1 contains a Si diode with a diode resistance on 1000. Use the piecewise linear model to solve the circuit. • How many nodes are in the circuit? • Determine the Thevenin voltage across the diode. Replace the diode with the appropriate model and then solve the circuit to determine the power dissipated by each resistor and the diode.

Find current I if voltage V = 5V, VB= 2V, R1& R2 = 2K. Use ideal diode model assumption.
