(b) The Thevenin equivalent circuit will now be determined for the network to the left of the terminals a-b without disturbing the structure of the network. All the measurements will be made at the terminals a-b. ETh ab Determine Eh by turning on the supply and measuring the open-circuit voltage Va Record the reading in Table 12.6. RTh FIG. 12.9 TABLE 12.6 Introduce the 1-k potentiometer to the network of Fig. 12.8, as shown in Fig. 12.9. ETh RTH ao Measured Calculation: bo Turn on the supply and adjust the potentiometer until the voltage V₁ is ETH/2, a con- dition that must exist if R₁ = Rh. Then turn off the supply and remove the potentiometer from the network without disturbing the position of the wiper arm. Measure the resistance between the two terminals connected to a-b and record as RT in Table 12.6, first column. 1-kΩ potentiometer www RL Calculated (c) Now we need to check our measured results against a theoretical solution. Calculate RT and Erh for the network to the left of terminals a-b of Fig. 12.8 and record in the second column of Table 12.6. Use measured resistor values. How do the calculated and measured values compare? (d) Now plot P, and V₁ versus R, to confirm once more that the conditions imum power transfer to a load are that R₁ RT and V₁ = ETth/2. Leave the potentiometer as connected in Fig. 12.9 and measure V₁ for all th of R₁ appearing in Table 12.7. Then calculate the resulting power to the load and comp table. Finally, plot both P, and V, versus R₁ on Graphs 12.2 and 12.3, respectively.

At the very least, disconnect one side of the potentiometer when making the setting.
