Transistors
A transistor can do these two things
What are amplify and act as a switch
When you disconnect a capacitor from a circuit, does the capacitor hold it’s voltage?
Yes, it holds its voltage
What does a diode do in a circuit?
Only allows electric to flow in one direction
Which way does conventional current flow?
What is the flow of electrons from positive to negative
A transistor is a way for a small amount of current to control this
A larger current
Where do electrons build up in the capacitor?
One side of the capacitor
This is the negative lead on a diode
What is the cathode
How does electron flow actually move?
What is the flow of electrons from negative to positive
The three pins of the transistor are...
What are the collector, base and emitter
Electrons will stop flowing through a capacitor when...
What is when the voltage of the capacitor matches the voltage of the battery
This is the positive lead on a diode
What is the anode
The element used in manufacturing most semiconductors
What is silicon
A transistor is normally in this position
Off or open position
This will happen if you use more voltage than the capacitor is rated for/can handle
It will explode
This part of the diode has more free electrons
What is the N-type
Mixing silicon with another element to enhance it's abilities is reffered to as...
What is doping
When are heat sinks used?
To switch higher amperage circuits
This is the unit of measure of capacitance
What is a Farrad
This part of the diode has more empty holes
What is the P-type
This electrical current flow theory is wrong but we use it anyway
What is conventional current
