When the base and collector supplies are equal, the transistor can be drawn as shown in Fig. 6-34b. What is the collector-emitter voltage in this circuit? The transistor power? (Give answers for the ideal and the second approximation.)
the daily output of a steam power station is 18x105 kwh. If the coal consumption is 700 tons per day calculate the thermal efficiency of power station .assume calorific value of coal 8500 kcal/kg
A trough is 8 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y=x^{8} from x=-1 to x=1 . The trough is full of water. Find the amount of work in foot-pounds required to empty
Write four balanced equations for this system - Identify where any constitutive equations may be required for the modelling processes.
When we discussed the work of Galvani and Volta, we noted that Galvani's work was not fully appreciated until the development of instruments capable of detecting and amplifying the small biopotentials present in living organisms.
Identify, design, simulate, and test a circuit. In this weeks lab you will identify, design, simulate and test a given circuit.
An amplifier with a power gain of 3dB is to be characterized. The test apparatus provides a SNR of 20dB at the input and measures a SNR of 15dB at the output. Find the amplifier's NF. Specifications for (2), (3), (4) and (5).
You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.70 s, and the velocity of the car decreases to + 4.71 m/s. The car's deceleration has a magnitude of 3.41 m/s2 during this time. What is the car's displace..
