In the following circuit find Ix and Iy by replacing the transformer and load at points x, x with the transformer load impedance.
Consider the following cicuit. Approximately how much current will flow through the 1Kohm resistor in parallel with the current source?
An operational amplifier has a gain 0f 20. The input voltage is 125mV and the input bias current is zero. The output voltage is 2.510V. What is the offset voltage?
Find I1, I2 and V3. I don't understand what terminal a and b would do to circuit? should i use mesh or node? I really don't where to start? see attachment for circuit ...
Should i start convert which part of the circuit using delta to Y method? Find V of R7? Please see attachment for circuit.
Find I1 and V3 - use Node Equation
If i were to use node equation, how do i go about to include the dependent sources in the equation.
Capacitor and electric automobile
We want to store sufficient energy in a .01-F capacitor to supply 5-hp for 1 hour. To what voltage must the capacitor be charged? (1 hp=745.7 watts). Does this seem to be a practical method for storing this amount of energy? Do you think that an electric automobile based on capacitive energy storage is feasible?
The current through a 3-uF capacitance is shown in the attachment. At t=0, the voltage is v(0)=10v. Sketch the voltage, power, and stored energy to scale vs. time. In the sketch of each one, I need the equations worked out for each plot. (See attached file for full problem description)
Prior to t=0, a 100- uF capacitance is uncharged. Starting at t=0, the voltage across the capacitor is increased linearly with time to 100V in 2s. Then, the voltage remains constant at 100V. Sketch the voltage, current, power, and stored energy to scale versus time. Please show equations for the sketches.
Attached is the problem...if you could help me understand it step by step and the graph as well please. thank you
