Description
Voltage: Voltage is the difference in charge between two points, measured in Volts.
Current: Current is the flow of electrons through a conductor or semiconductor,
measured in Amperes or Amps. Some materials conduct current better than others;
these are known as conductors, semiconductors, and insulators. Current flow is from
positive to negative. Power: Power determines how much work a circuit can do. It is
measured in Watts.
