- Ohm's Law states that the current flowing through a conductor, or resistance, is linearly proportional to the applied potential difference (volts).
- Electricity is delivered to our homes and businesses as AC (alternating current). Computers use DC (direct current).
- Electricity always seeks the path of least resistance to ground. An electrical outlet or an extension cord without a ground wire is unacceptable for use with a computer.
- A multimeter is an instrument used to measure electrical voltage, current, resistance, and continuity.
