0-100mAdc mA 1K 20Vdc R, IK Fig. 14-2
Transcribed Image Text:0-100mAdc mA 1K 20Vdc R, IK Fig. 14-2
Refer to Fig. 14-2. If fesistor R2 was not in the circuit, what would happen when the rheo- stat was adjusted for minimum resistance? Can a potentiometer be used to replace a Explain. 2. 6. rheostat? 7. What is meant when a potentiometer is described as having a linear taper? 3. If resistor R2 of Fig. 14-2 had a value of 100 ohms, would you change the range setting of the milliammeter? Explain. A logarithmic taper? 4. Rheostats control (current, voltage). Refer to Fig. 14-5. If an ammeter was con- nected between switch S, and potentiometer R1, and 8. how much current would it indicate at E (min) Can a rheostat be used to replace a poten- Explain. 5. ? E (max) tiometer? 'E (min) = mAdc %3D mAdc %3D E(max)
