Diagnosing a loss of the computer's reference voltage is being discussed. Technician A says that the VREF signal should be between about 4.2 and 5.2 V. Technician B says that the VREF signal should be between about 5.2 and 9.6 V. Who is correct?
A. Technician A only B. Technician B only C. Both A and B D. Neither A nor B
Whenever a technician has an electrical system problem that directly concerns the computer, a testlight is handy.
Answer the following statement true (T) or false (F)
Answer the following statement(s) true (T) or false (F)
1. Many digital ohmmeters measure the value of a resistor by passing a known amount of current through it and then measuring the voltage drop across the resistor. 2. Analog sensing devices are sensors that are designed to operate between some range of settings. 3. Long runs of wire have the effect of reducing resistance to the lines. 4. A current generator can be constructed using either a field effect transistor or a junction transistor. 5. A pnp junction transistor cannot be used to construct a current generator.
