  • series circuits
    • one big loop
    • potential difference (P.D)
      • SHARED
        • various components
      • add them all up to find total
      • V=V1+V2
    • current
      • SAME EVERYWHERE
        • all components
      • size determined
        • total P.D of cells and total resistance of circuit
          • I=V/R
          • all components get same current
      • A1=A2=A3
      • doesn't add up
        • 2A x 2 = 2A
    • resistance
      • ADDS UP
      • the bigger the resistance
        • bigger its share of P.D
          • more work is done by charge
      • variable resistor/light-dependant resistor/ thermistor
        • P.D across all components will change
      • R=R1+R2+R3
    • voltage
      • ADDS UP
      • connect several cells
        • the same way ( + to - )
        • bigger total voltage
          • each charge in circuit passes through all cells
          • gets a 'push' from each cell
      • 2 x 1.5V = 3V in total (example)
