  • parallel circuits
    • "separate connections"
    • potential difference (P.D)
      • EQUAL
        • across each component
        • all bulbs will be at the same brightness
      • V1=V2=V3
    • current
      • SHARED
        • between branches
      • A=A1+A2
      • adds up
        • 2 x 0.5A = 1A total (example)
    • resistance
      • TRICKY TO WORK OUT
      • less than branch with smallest resistance
      • circuit with 2 resistors in parallel
        • lower resistance
        • higher current
      • total R < R total R < R2
    • voltage
      • charge only goes through one celll
      • 2 x 12V = 12V total (example)
