Lesson Title: Today we are learning about
How can we calculate the power of an appliance?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Students should be able to explain how the power transfer in any circuit device is related to the potential difference across it and the current through it, and to the energy changes over time: power = potential difference ? current P = V I power = current2 ? resistance P = I2 R where: power, P, in watts, W potential difference, V, in volts, V current, I, in amperes, A (amp is acceptable for ampere) resistance, R, in ohms, ? Everyday electrical appliances are designed to bring about energy transfers. The amount of energy an appliance transfers depends on how long the appliance is switched on for and the power of the appliance. Students should be able to describe how different domestic appliances transfer energy from batteries or ac mains to the kinetic energy of electric motors or the energy of heating devices. Students should be able to explain how the power of a circuit device is related to the potential difference across it and the current through it

Keywords:

Ohms: the SI unit of electrical resistance, transmitting a current of one ampere when subjected to a potential difference of one volt. (1)
Current: The ordered directional movement of electrically charged particles. (1)
Power: The amount of energy transferred per unit of time. (Expressed in Watts) (1)
Charge: The physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges; positive and negative. (1)

AFL/Key Questions:

What are the two equations used to calculate power?
The two equations used to calculate power are: P = V I power = potential difference x current P = I2R power = current squared x resistance where: power, P, in watts, W potential difference, V, in volts, V current, I, in amperes, A (amp is acceptable for ampere) resistance, R, in ohms,
What is the purpose of everyday electrical appliances?
The purpose of everyday electrical appliances are to bring about useful energy transfers.
What does the amount of energy an appliance transfers depend upon?
The amount of energy an appliance transfers depends on how long the appliance is switched on for and the power of the appliance.
How do domestic appliances transfer energy from batteries or mains to the kinetic energy of electric motors or heating devices.
domestic apliances such as a washing machine will transfer electrical energy from the mains to kinetic energy, thermal energy and sound energy of the motor inside to turn the drum.
How is the power of a circuit device related to the potential difference across it and the current through it?
P = IV so Power is the sum of the current mulitplied by the potential difference ( potential energy x rate of flow)
