Chapter 16, Problem 18R
In order to wire a post light, a homeowner purchased some single-conductor cable that was marked as suitable for direct burial in the ground. A separate equipment grounding conductor to the post light was not carried. Instead, the bottom of the metal post, buried 2 ft (0.6 m) into the ground, was used as a ground for the post light. The inspector “red tagged” (turned down) the installation. Who is right—the homeowner or the electrical inspector? Explain. ___________________

Examine the data sheet for this device carefully. In particular, make a note of the current gain (identified by hFE). 1. Obtain the curve trace for a "Darlington Pair" of Bipolar Junction Transistors. A Darlington Pair consists of two transistors with the first BJT driving the base terminal of the second transistor as shown in Figure 1 below. A. Set up the primary sweep voltages for V1 the same as shown in the lecture notes (see the Darlington pair IV curve). B. Set up the secondary sweep currents for 11 to be an order of magnitude smaller than for the single BJT. In the Sweep Type box choose linear and enter the following 3 values: Start Value: 0, End Value: 8u and Increment: 1u (see lecture notes). C. Describe the primary differences you observe between the single BJT Curve Trace and that of the Darlington Pair. Discuss what might cause each difference. Q1 11 Q2 V1 Q2N3904 Figure 1.

We also require the power supply to be fixed at 5 Volts (this is where the load line intercepts the iB =ic = 0 line). You may use the circuit shown in Example 1. Note that all resistor values in Example 1 must be recalculated. Your solution for the base to ground and base to collector resistors may not be unique.arrow_forwardA circuit is given as shown.
