Consider the circuit in Figure 2. Resistor R1 has a value in Ohms equal to the last two digits ofyour SID. For example, if your SID is 200123145, then R1 = 45 2. If your SID ends in 00, then use a value of R1 = 80 2. A variable resistor Ry is connected to the circuit output and is tuned until maximum power transfer is achieved from the circuit.

Calculate the value of Ry required to achieve maximum power transfer. Show your working. Determine the power dissipated by Ry in Figure 2. Show your working.
