at room temp a power transistor has beta of 160 and it is used in a DC dimmer circuit to control a 24 volt 120 watt lamp the lamp power supply is 48 volts dc and it can deliver a maximum of 21 amperes of current
A)Sketch diagram of lamp at 100 percent brigthnesss
B)calculate lamp current of 100 percent brightness
C)find base current of transistor
D)how much power is dissipated by the transistor
E)what happens when the transistor heats up
F)if the transistor shorts out between the collector and the emitter what happens to the lamp
G)can the lamp be protected
Given the following function in canonical SOP form, h = a'bc' + a'bc + ab'c + abc' + abc use Boolean algebra to simplify h down to a minimum SOP expression that contain only 2 terms and 3 literals.
The program will store these values into an array and call a function that will return the average of the temperatures. It will also call a function that will return the highest temperature and a function that will return the lowest temperature.
A power supply, when connected to a radio, provides 5V to the radio. When connected to a lamp, it provides 4V to the lamp. Assume the radio can be modeled as 6ohm resistor and the lamp can be modeled as a 0.7ohm resistor.
A three phase motor draws 20kva at 0.7 lagging power factor from a 240 V source. Determine the kVAR rating of the capacitors to make the combined power factor 0.9 lagging and determine the line current before and after the capacitors are added.
Design an ac-dc voltage converter based on half-wave rectification and filtering. The requirements are: 1. Choose the values of the load resistor R and the capacitor C so that the converter will have a ripple factor of 10%
A. Determine the transfer function H(z) for this system. B. Determine the z transform Ys(z) of the step response for this discrete time LTI system using complex domain (not time domain) analysis techniques.
A sheet of plywood 1.39 cm thick is used to make a cabinet door 55.5 cm wide by 69.5 cm tall, with hinges mounted on the vertical edge. A small 181-g handle is mounted 45 cm from the lower hinge at the same height as that hinge.
Two watt-meters connected to read the total power drawn by a balanced three-phase load. If the two readings are 1000 W and -1000 W, what is the total power drawn by the load
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
design a circuit to sort a product which has 2 different color in two diffrenet boxes for example red and green apples no any microcontroller or microprossser are allowed. which color sensor is the best to have 5 volt output so a solenoid may work..
An amplifier with a voltage gain of +40 dB, an input resistance of 10 k ohms and an output resistance of 1 kohm is used to drive a 1 k ohms load. what is the value of Avo. Find the value of the power gain in decibels.
