Basic Electronics Flashcards
Benefits of solid state electronics?
Small, need little power to operate, reliable, don’t generate much heat
A semiconductor is produced when a small amount of another material is added to the covalent-bonded silicon crystal. This material is added in selected amounts to control conductivity in a process called?
Doping
How do you check a resistor?
With an ohmmeter
A variable resistor that has two connections is called a:
Rheostat
A variable resistor that has three connections is called a:
Potentiometer
potentiometers divide ______, rheostats control _______
voltage, current
When testing a resistor, the reading is lower than rated. What does this indicate?
A short or ground fault
When testing a resistor, the reading is higher than rated. What does this indicate?
An open or high resistance
What are two functions of a diode
forward and reverse bias
what is
anode
cathode
Anode= positive
Cathode= negative
What is reference voltage?
constant voltage sent to sensors from ECM. usually 5v
What is a voltage generating sensor?
A sensor that creates its own analog voltage signal. It is an input signal
What is encoding?
Analog to digital
