Cards

Term
Conductors
Definition
allow free flow of electrons; ex. Metals
Term
Insulators
Definition
impede flow of electrons; ex. Rubber
Term
Resistors
Definition
devices that will conduct some current if you encourage the electrons with a potential difference
Term
Semiconductors
Definition
poor conductors and poor insulators, can be used for either or both properties
Term
Potential difference
Definition
motivation for charge to flow
Term
Voltage
Definition
potential difference
Term
gate, drain, source
Definition
3 terminals of a transistor
Term
gate, drain, source
Definition
Voltage applied to _____ allows current to flow between the _____ and _____.
Term
Diode (pn-junction)
Definition
a union of P-type and N-type material; functions as a one-way "valve" in an electric circuit
Term
Depletion region
Definition
E-field that impedes the flow of current
Term
Forward bias
Definition
depletion region gets smaller, allows current to flow from + to -, allows flow of electrons through junction
Term
Reverse bias (reverse the battery)
Definition
depletion region gets bigger, impedes flow of current from + to -, impedes flow of electrons through junction
