  • P2
    • CIRCUITS
      • Current= flow of charge around the circuit.
        • Unit: Amperes,A
      • Potential difference=driving force that pushes current round
        • Unit: Volts,V
      • Resistance= anything that slows down current.
        • Unit: Ohms
      • Greater the resistance, the smaller the current.
      • Potential difference is V.  VOLTAGE
        • Resistance increases with temperature
      • Currents only flows in one direction through Diode
    • SERIES
      • All voltage is shared over circuit
      • Current is the same everywhere
    • PARALLEL
      • Voltage is the same
      • Current is shared between branches
  • Resistance increases with temperature
