resistance

• the resistance of a component is the measure of how

  it resists the flow of charge

  
• the higher the resistance the

  more difficult it is for charge to flow

  
• the higher the resistance the

  lower the current

  
• resistance is measured in

  ohms

  
• potential difference tells us the

  difference in electrical potential from one point in a circuit to another

  
• potential difference is measured in

  volts

  
• potential difference can be thought of as an

  electrical push

  
• the bigger the potential difference across a component

  the bigger the current

  
• the grater the the potential difference

  the greater the flow of charge

  
• potential difference is measured using a

  voltmeter
