Chapter 7, Problem 33P

For the potentiometer in Fig. 7.95:

a. What are the voltages Vab and Vbc with no load applied

$(RLA=RL2=\infty \Omega )?$

b. What are the voltages $V_{ab}$ and $V_{bc}$ with the indicated loads applied?

c. What is the power dissipated by the potentiometer under the loaded conditions in Fig. 7.95?

d. What is the power dissipated by the potentiometer with no loads applied? Compare it to the results of part (c).
