Shut off circuit

Refer to the following circuit: Assume that the switch has been open for a long time, and that it closes at time t=0 seconds. The switch remains closed thereafter. Solve for vx(t), and ix(t) as shown in the circuit diagram. See attached file for full problem description.

Parallel Resistors - 13.1

See attached file for full problem description. I think th problem is solvable by observation f. use the property that at low frequency the inductors act like a short circ and open circ in high freq. Vice versa for capacitors.

NEMA(NEC) code

In the NEMA(NEC) code there is a procedure to size fuses, motor starters, and overloads knowing full load amps. How is this done using ohms law. Say full load amps is 2.6A which we have at work. We looked at the NEMA code and it said do 125% times 2.6A then 125% times that , but using ohms law what is going on? To know what f ...continues

Vs(t)=Acos(w1t)+Bcos(w2t). See attached file for full problem description.

Opamp transfer function magnitude and phase.

Consider the circuit. The opamp is ideal. Find the transfer function H(w)=Vo(w)/Vs(w). Find the magnitude and phase of H(w). Plot the magnitude (dB) and phase of H(w) on a Bode plot (vs log w). What type of filter is this? See attached file for full problem description.

Unity Gain Inverter.

Consider the unity gain inverter made with an opamp. The opamp is ideal except A(w) = B/jw where B, the unit gain bandwidth of the opamp, is a constant (rps). Find the transfer function H(w)=V0(w).Vs(w) as a function of A. Substitute the expression for A(w) and find the magnitude and phase of H(w). Plot the magnitude (dB) and ph ...continues
