The amount of electrical energy is a circuit depends upon three things:

  • the voltage (in volts)
  • the current (in amps)
  • the time (in seconds)

If any one of these increases then so does the amount of electrical energy.

Because current and voltage can be  controlled easily, therefore it is one of the most
