A transistor or semiconductor curve tracer. Since the diode is open before breakover, no 6. The input is larger than the maximum allowed power will increase. See figure below. The barrier potential is 0.
The transistor is dissipating mW. As long as the voltmeter has a high enough input resistance, it should read approximately 4. Increase the power supply value, short R1. Connect an ammeter between the power supply and the Answer: The collector-emitter voltage is —4.
Measure VR1 and VC, then calculate and add their the collector is less positive than the emitter. The output voltage is 8. The collector voltage for Q1 is 9. Since the base voltage is 1.

Power gain is the product of voltage gain and current gain. Trouble 1: Since all the ac voltages are 0, the problem Although the voltage gain is slightly less than 1, the current could be the generator, RG open, or C1 open. Therefore, the power gain is very large. Trouble 2: Since the input voltage increased to 0.

Since the input is clamped at 0. The average value is —6. The input voltage is The dc input power is 15 mW. The resonant frequency is The resonant frequency is 7. The bandwidth is This gives Answer: The worst-case power dissipation is To find the ac saturation current, take the ac See the graph.
The worst-case power rating is mW. Derating curve on Fig. The power across the load resistor should increase because the emitter current is increased, the gain is Since the dc input power is increased and the output Answer: The power rating is The input is larger than the maximum allowed power will increase. The input is driving the output into saturation, clipping the wave off, and turning PD: Electrically, it would be safe to touch, but it PS: A higher R1 will cause the input power to decrease may be hot and cause a burn.
No, the maximum efficiency of anything is MPP: A higher R1 will cause the emitter voltage to percent. It is impossible to get more power out of a decrease and thus the emitter current to decrease. This device than is put into the device.
No, the ac load line is more vertical because the ac collector resistance is usually less than the dc: Since the dc input power is decreased and the output collector resistance. If the collector had an inductor power is decreased, the efficiency is not changed. The drain voltage is 0. The drain voltage is The drain voltage is 7. The gate-source voltage is —5.
