Find the load impedance 2L for the network shown in Figure 2 for delivering maximum power to the load. Also calculate the maximum power supplied to the load. What is the percentage of power loss when supplying maximum power to the load. REAL M 000 4.12 312 E 230 V 20 X 612 ZL Figure 2: Circuit for Question 2

Rg = 50ohm
Max power is transferred when load is complex conjugate of
system resistance
Therefore for Load Impedance,Zl = 50 -
j*(2*pi*2.5*10^3*5*10^-3)
=> 50 - 78.54 j
Resistance in Load,R = 50 ohm
Capacitance in Load,C = 8.106*10^-7 F = 0.8106 micro
