Power

• • As the potential difference or current increases, the power transfer also increases.
  • the more power being transferred over time, the more energy is being used or converted in the circuit
• Equation linking power, potential difference and current

  • power = potential difference x current

  power in watts, potential difference in volts and current in amp.
• Equation linking to power, current and resistance:

  • power = (current) squared x resistance

  power in watts, current in amp and resistance in ohms
