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
