- This is not a graded assignment. Its a mock exam. I need help with both parts of the question: my current apporach thinking is that. To find the maximum average power transfer to the load I know we would first find the Impedance values of all the components and than add them up and than finally find the conjugate of that value correct? But im not sure how to find Pmax than based on what i got for part 1. Some guidance here would be appreciated. Im also not sure if my part 1 is correct either so i would apperciate assitance on that question as wellThe ratio of the forward voltage to the forward current is called the characteristic impedance? What is forward voltage? What is the forward current? What is characteristic impedance?A high voltage engineer cascades having 6 stages Each in the circut . each stages capacitance is 15 nF and Input voltage to the circuit is 100kV at 100 Hz and the load current is 1mA. so this voltages not enough with one moudle .
