Energy Transfer - From Source to Load
This is one of a series of focused units, from the Association for Science Education and the Design and Technology Association, to introduce students to important technologies and their applications. In their study of this unit students can improve their understanding of energy transfers and the efficiency of energy transfers. Students are also introduced to processes for analysing mechanical systems and for selecting electrical cells for a particular purpose.
The technological applications of the science in this unit include:
• matching a power source to a load,
• controlling the transfer of energy, and
• analysing mechanical systems in terms of inputs and outputs.
• Plan of the unit
• By using the unit students will ...

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
