It can take the form of a sudden discharge of static electricity, like a lightning bolt or a spark between your finger and a ground light switch plate.

  • What is Voltage?

    What is Voltage?

    In short, voltage can be thought of as a force that pulls electricity (current) around a circuit. If a high voltage is applied to a circuit, then it will experience a high flow of electricity (i.e. current flow). If a lower voltage is applied to a circuit, then it will experience a lower flow of electricity. There is a good analogy for voltage that...
