Power

  • 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.
