calculating energy transfer by components

• Calculating total energy transferred by components

  1. Calculate total charge flowing in circuit

  2. Use equation: Energy transferred (J) = Charge flow (C) x Potential difference (V)

  3. Apply equation to specific components
• Charge flow


  The total charge flowing in a circuit, calculated as: Charge (C) = Current (A) x Time (s)
• Whenever charge flows in a circuit, work is done and energy is transferred
• The equation for energy transferred is not given in the exam, so it must be learned
• In a series circuit, the potential difference is shared across the components
