Due to its wider bandgap than silicon, a GaAs red light emitting diode (LED) typically has a turn-on voltage of 1.6 V. Assuming the maximum allowable current through the LED is 16.7 mA,
The current amplification factor β of a BJT is very sensitive to the base width as well as to the ratio of the base doping to the emitter doping. Calculate and plot β for a p-n-p BJT with Lnp = Lpn for: (a) nn = pp and Wb/Lnp = 0.01 to 1
Design an amplifier capable of providing the specified gain over a frequency range of 20 Hz to 10Khz under the following conditions. Input source is 2700ohms resistive, and the output load impedance is 32ohms resistive.
estimate results in the lights being switched on for an average of 19 hours per day - 6 hours more than needed. The room is lit with seven, 60 W incandescent bulbs, which you can assume are powered by a 115 V constant voltage source.
For each of the sinusoidal source functions, determine the complex exponential source that has the given source as its imaginary part. Determine the phasor representation of each of the sinusoidal source functions.
The generator voltage is 120 V and the lamp voltage should be 110 V or more. Calculate the current drawn by each lamp if its voltage is 110 V and its power is 100 W. Calculate the current in the two-wire line. Calculate the maximum resistance of t..
