Electric current basics

Electric Current: Basics


Current electricity

Current Electricity

  • Current electricity is like current in a river.

  • A high or fast river current means the water is rushing past the shore quickly.

  • A high current in electricity means that the electrons are moving past points in the circuit quickly.


Current electricity1

Current Electricity

  • Electrons keep moving around the circuit with a constant source of energy (ex. Battery, power outlet, etc.)

    • Energy gives the electrons a ‘push’


Current electricity2

Current Electricity

  • Current: the rate of electron flow past a given point in a circuit


Current electricity3

Current Electricity

  • Symbol: I

  • Units: Amperes (A)

  • Measured with: Ammeter


Potential difference

Potential Difference


Potential difference1

Potential Difference

  • Potential Difference/Voltage: the difference in electrical energy per unit charge measured at two different points

  • Symbol: V

  • Units: Volts

  • Measured with: Voltmeter


What is an electric circuit

What is an Electric Circuit?

  • An electric circuit is a continuous path through which an electric current is passed

  • Electric circuits convert electrical energy into other forms of energy we need – such as heat or light.


Parts of an electric circuit

Parts of an Electric Circuit

  • There are five basic parts found in a simple electric circuit.


Parts of an electric circuit1

Parts of an Electric Circuit

  • Energy Source

    • Provides electrical energy in a circuit

    • E.g. battery, electrical outlet

Battery

(energy source)


Parts of an electric circuit2

Parts of an Electric Circuit

  • Load

    • An electrical device that converts electrical energy into another form

    • E.g. light bulb, motor
