Question

Please help me answer these questions and show all work.

Find the Thevenin's Equivalent circuit to the left of ZL for the circuit below: Given I = 6A. Determine the ZL for maximum power transfer to ZL. Calculate the maximum power to ZL. Given this circuit, calculate the Thevenin's (@A, B) equivalent circuit. What RL will provide the maximum power transfer? Using this circuit calculate the equivalent resistance Req and currents: IR18 and Ir leaving the battery. Calculate the equivalent impedance Zeq polar coordinate from for this circuit. f= 6 KHz. What is the resonant frequency fr? Using this circuit calculate voltage across the 80Ohm and 10Ohm resistor and the current through the 5Ohm and 600 Ohm resistor.

Explanation / Answer

a) Vth= 32.199_-116.56

Zth= 12_-53.13

b) ZL=7.2+j9.6

c) pmax= Vth^2/4RL =32.199^2/4*7.2 =35.99watt
