6.2.4.2 Energy transfers in everyday appliances

Content	Key opportunities for skills development
$Everyday electrical appliances are designed to bring about energy transfers. The amount of energy an appliance transfers depends on how long the appliance is switched on for and the power of the appliance. Students should be able to describe how different domestic appliances transfer energy from batteries or ac mains to the kinetic energy of electric motors or the energy of heating devices. Work is done when charge flows in a circuit. The amount of energy transferred by electrical work can be calculated using the equation:$
$\text{energy transferred}=\text{power}\times\text{time}$
