Electricity or the Flow Of Electrons (negative charge) is what powers all of technology created by Benjamin Franklin in 1752 with a kite and a key. Energy on the other hand, is what makes all things move and work. Today, people who work with electricity and energy use them both to create helpful and useful devices like light bulbs and computers for our daily lives.
What Is Voltage?
Voltage is the difference in potential between two points of a circuit. It can also be classified as the pressure behind the Flow Of Electrons. Symbol for Voltage is V or E (Ohm's / Watt's Law), and the Unit of Measurement is Volts.
What Is Current?
Current is the amount of charge in a circuit or the amount of Flow Of Electrons is in a circuit. Symbol for Current is A or I (Ohm's / Watt's Law), and the Unit of Measurement is Amperes or Amps for short.
What Is Resistance?
Resistance is the opposing force against the Flow Of Electrons. The symbol for Resistance is R or Ω. And the unit of measurement is Ohms.
