vocabulary
100
what is a semiconductor
materials that contain exactly 4 electrons in the outer orbit
100
what is the difference between a converter and an inverter?
inverter makes d/c to a/c converter makes d/c to d/c or a/c to a/c
100
what is pressure
volts
100
what does 0 and 1 mean
0 means off 1 means on
100
define amperage
the total amount of current flowing in a circuit
200
what is the difference in a diode and a zener diode
diode allows flow one way but not back the other way, zener diode will allow flow back
200
capacitors are also called?
condenser
200
what is flow?
amps
200
explain a not gate
output is opposite to the input so if input is 0 then output is 1
200
define continuity
a continuous path for the flow of an electrical current
300
how does a photo diode work?
they respond to light
300
how is capacitance measured?
in farads, or F
300
how do you hook up the meter to measure flow?
in series
300
explain an and gate
both inputs have to be 1 for the output to be 1
300
define diode
a semiconductor which permits current to flow in one direction only
400
how can you test diodes?
with an ohmmeter
400
true or false: capacitors in parallel effectively decrease the capacitance
false. capacitors in parallel will increase the capacitance
400
what is a simple circuit
series circuit only one path for current to flow
400
explain a nand gate
both inputs have to be 1 and the output will be 0 or both inputs be 0 then output would be 1
400
define p- type material
a material used in the construction of semiconductors in which the hole density exceeds the conduction electron density
500
what are the four causes of premature failure in electronic components?
poor connections, heat, voltage spikes, excessive current.
500
a capacitor used for spike protection will be placed in _______ to the load or circuit
parallel
500
the forward-bias voltage required for an led is?
1.5-2.2 volts
500
would this be 1 or 0?
1 on
500
define Rheostat
a resistor for regulating a current by means of variable resistances
