Solve the given circuit practice problems:
1. Find the values below. Show your work, which may appear right on the schematic.
a) R1= ?b) R3= ?c) VS= ?d) PS= ?
2. Use the method of superposition to find the current through R1 (IR1) and the voltage across R3(VR3). Be sure to clearly show and circle your intermediate results.
3. a) Find and draw the Thévenin equivalent of the circuit shown. The load resistor is RL
b) Find and draw the Norton equivalent of the same circuit.c) Find the load current using your Thévenin equivalent circuit. d) Choose a different value of RL so as to maximize the power dissipated in RL . Find that maximum power, PL .4. Use nodal analysis to find the voltage across R2 (VR2). You MUST show all the steps of nodal analysis work to get credit, including drawing appropriate symbols and labels on the circuit shown.
b) Find the current through R3(I3). 5. The circuit below has been connected as shown for a long timea) Find the voltage across each capacitor.b) How much energy is stored in capacitor C2 .
Discuss the possible difficulty of such an approach.
a 4 bit binary number is represented as A3,A2,A1,A0 whereA3,A2,A1 and A0 represent the individual bits where A0 is LSB. design a logic circuits that will produce HIGH output whenever the three binary number is greater than 0010
Two bar magnets are placed in a straight line with their morth poles 5 cm apart. (a) what is the force of repulsion if M1=25.1*10^-5 Wb and M2=6.28*10^-5 Wb. (b) what is the field intensity at the M2 north pole as a result of the M1 north pole.
A manufacturer specification sheet lists the transfer function of a pressure sensor as 45±5% mV/kPa with a time constant of 4±10%. A highly accurate test system applies a step change of pressure from 20 kPa to 100 kPa.
An AC sine wave is applied to the input of a full wave rectifier. The output of the full wave rectifier is then applied to a half wave rectifier.
Controlling interest rates is an example of
Suppose that the sequence 110010011 is used as a synchronization sequence preamble to a data packet. Propose a method that can be used to allow the channel to distinguish the synchronization sequence from an identical data sequence within the pack..
An Aluminum electrolytic capacitor that has a capacitance of 75,000µ F,100WV is used in a power supply circuit. The leakage specification of this type of capacitors is 5µ A/µ F. If the voltage across this capacitor is 50 volts, what will be the le..
An OpAMP has a unity gain frequency (ft) of 10MHz and a slew rate of 10V/us and AVoc = 120dB at DC (f=0). Assume VCC = -VEE = 15 Volts.a. Approximate the cutoff frequency of the OPAMP itself. b.
Using the solution for , write an expression for the H field of the wave in medium 2, which is due to the surface-current source. Hint: Since the current-sheet source is independent of x and y, so will be the wave it generates - this is a plane wa..
