1) For the circuit of Figure 1, obtain the Thevenin’s equivalent circuit (i.e. RTH and VTH) between nodes A and B.
2) For the circuit of Figure 1, draw the Norton’s equivalent circuit seen between nodes A and B.
3) Using the Thevenin’s equivalent circuit of (part 1), predict the current in the diode.
Relevant Data for the LED, ZD0100
4) If the diode in Figure 1 is replaced with two serially connected diodes, predict the currents in the diodes. Will the diodes light up?
5) The LED in Figure 1 is replaced with a resistor RL. Predict the voltage across RL and the current in RL for RL = 4.7kW, 10kW, and 47k W respectively. (find VRL AND IRL for each resistor)
