Problem DP 3-1

The circuit shown in Figure DP 3-1 uses a potentiometer to produce a variable voltage. The voltage vm varies as a knob connected to the wiper of the potentiometer is turned. Specify the resistances R1 and R2 so that the following three requirements are satisfied: 1. The voltage vm varies from 8 V to 12 V as the wiper moves from one end of the potentiometer to the other end of the potentiometer. 2. The voltage source supplies less than 0.5 W of power. 3. Each of R1, R2, and RP dissipates less than 0.25 W. R1 R2 24 V RP Voltmeter + vm + Figure DP 3-1
