This is a set practice calculations that test pupils' use of the equation:
Cost = Power x Time x Price per Unit
There are 3 similar Question Sheets which each consist of 20 written questions and a single sheet containing the numerical solutions to the 3 batches of questions.
The sheets are designed to reduce photocopying/printing costs by using small margin size and tight line/paragraph spacing. However, the document may be edited to any format desired using a word processor.
The sheets are aimed at giving able pupils at GCSE or A-Level plenty of practice in this topic prior to their exams. To this end, the units used are varied to include:
Power in W or kW and Time in seconds, minutes, hours, days, weeks.

About the Author
I am a physics specialist (Ph.D.) and since 1985, have taught in the Royal Navy (as an Instructor Officer), independent and state schools. I have regularly taught all 3 sciences up to GCSE and Physics to A-Level. I served as head of physics in one school for 20 years. Over the years I have also taught ICT, GCSE Electronics, GCSE Astronomy and some A-Level Further Maths (Mechanics).
I have always created resources to supplement those in texts/ published schemes.
