  • Power in circuits
    • Power of device depends on...
      • Potential difference across it
      • Current running through it
    • Higher potential difference
      • Uses more energy per second
        • More powerful
        • (Than one with less)
          • Uses more energy per second
            • More powerful
    • Higher current running through
      • Uses more energy per second
        • More powerful
    • Power = potential difference X current
      • P = VI
    • Power = (current)^2 X resistance
      • P = (I)^2 X R
    • Measured in Watts
