Following the derivations leading to Equation, prove that the other 50% of the supply power is dissipated by the transistor itself.
= 50%.
1) in a swamped common-emiter BJT amplifier, as shown below, if Vcc =12 V, R1 =8.2 kohm, R2=10 kohm, Rc = 500 ohm, Re= 1 kohm, Vbe = 0.7 V, and B =100, what is the transistor`s emitter current
A coaxial line 5.6m long has distributed parameters R=6.5ohm/m, L=3.4 uH/m, G=8.4 mS/m, and C=21.5 pF/m. If the line operates at 2MHz, calculate the characteristic impedance and the end-to-end propagation time delay.
Design a Miller integrator with a time constant of 0.1 s and an input resistance of 100 k ohm. A dc voltage of -1 volt is applied at the input at time 0, at which moment vO = -10 V. How long does it take the output to reach 0 V to +10 V
Determine the transfer function for a first-order high filter with a cutoff frequency of 1000 radians per second and passband gain of 1 using the following types: a. 3-dB Butterworth type. b. Chebyshev type with 1 dB ripples on the passband.
Find Vx across the resistance R3 = 10Ω, using in network figure.- Nodal analysis- Mesh analysis -Superposition- Thevenin theorem- Norton theorem.
a curemt of 1600a exists in a recatangular 0.4 by 16cm bus bar. the current is due to free electrons moving through
For the circuits shown in the figures indicated, label the nodes and meshes and write the ac steady-state KCL and KVL equations. Write all equations in terms of the phasor currents and the source phasors.
Determine the load for maximum efficiency and the iron-and the copper-loss in this case.
You are installing a new spark plug in your car, and the manual specifies that it be tightened to a torque that has a magnitude of 84 N·m. Using the data , determine the magnitude F of the force that you must exert on the wrench.
The network is toanalyze each sequence of four binary digits and produce the corresponding 2's complement of the 4 bit sequence. Assume each 4bit sequence is occurring with the least significant bit first. An example that would satisfy the network
1. How is the LCD placed into the 4-bit data mode? 2. How is the cursor in an LCD positioned to a specific, user-selected location on the display? 3. Given the state of RS, E and R/W~, and the data (in hex) needed to send an 'H' to the LCD for disp..
A motor is supplying 50 N × m of torque to its load. If the motor's shaft is turning at 1500 r/min, what is the mechanical power supplied to the load in watts? In horsepower?
