Simple Circuit

• Power Source


  provides electrical energy needed for the circuit. eg battery
• Conductors


  a material allowing movement of charge
• Insulator


  material opposing the movement of charge
• Load


  The component that consumes the electrical energy to perform work e.g. light bulb
• Switch


  controls blah blah
• Resistor


  component restricting flow of current
• Amperemeter


  used to measure flow of current
• Voltmeter


  instrument used for measuring the electrical potential difference between two point in a electrical circuit.
