Current
The amount of charge moving past a point in a conductor in a unit of time
Resistance
The property of materials that opposes or impedes the flow of electric current
First Great Truth
The sum of the component voltage drops in a series circuit is equal to the voltage of the source.
Second Great Truth
The greater the resistance of a resistor, the more voltage it drops
Third Great Truth
In a series circuit, the percentage of resistance contributed by a component is equal to the percent of voltage dropped by that component.
Short Circuit
Any pathway that is made of wires only without regard to it's length
Role of a resistor
To oppose or impede the flow of electric current
Voltage Drop %
Voltage drop of component/Total Voltage in circuit
Ohm's Law
V=I*R
