The difficulty was not terrible as I feel I was able to get most if not all answers correct. Moins

National Grid

I was given a map, illustrating a part of electricity network at the border of England and Scotland. The Scenario was loosing a 400 kV line and its subsequent effects on other 132 kV line and the connected network.The question was what should be done to decrease the effect of this outage? What lines or demands should be (probably) shut down? Explain the protection measures in such case.

MaxLinear

Suppose you have a transconductance amplifer with infinite input impedance and transconductance Gm. There is a feedback resistor from output back to input (Rf). There is a load resistor from the output to Ground (RL) . Find the input impedance as a function of Gm, Rf, Rg.

1 réponses

start out with special cases. if Gm* RL = 1, then Vout = Vin and Zin = infinite. If Gm = 0, then Rin = RL+ Rout To get general solution, use KCL and KVL Moins
