P4

• Static electricity


  A buildup of electric charge in a material that is not free to move.
• how to find charge

  current x time
• equation for potential difference?

  V = IR
• Resistor


  Allows current to flow in both directions, has linear behavior, and constant resistance if temperature remains the same.
• Diode


  Only allows current to flow in one direction, blocking current in the opposite direction.
• Thermistor


  Resistance decreases as temperature increases.
• Light Dependent Resistor (LDR)

  Resistance decreases as light intensity increases.
• Series Circuit

  Current flows through all components in sequence

  total current stays the same, potential difference changes

  total resistance is sum of individual resistors.
