This resource can be used to develop recall and application of the electricity equations in GCSE Physics:
V = IR
P = VI
Q = It
E = Pt
E = QV
The formula triangles are shown on the worksheet but can easily be removed if appropriate. The task involves students calculating all of V, I, R, E, P, t from a given set of values. It requires students to think about how they can work out a missing variable based upon what they’ve been given. The values used in the worksheet tend to be small whole numbers so this worksheet can be completed without a calculator for extra challenge.

Great resource, thank you. First page of preview is the answer sheet, second page has missing gaps for pupils to fill in. I've added some instructions to print back to back with p2 for the pupils. Feel free to use or adapt these if you like :-) Instructions: This task is to give you practice on using formula triangles. Look at the formula triangles at the top. These are all real formulas but you don’t need to know what the symbols stand for to do the sums! If you want to, add lines, x and ÷ to the triangles to help you use them. Look at the data in the columns. For each set you can use at least two triangles. What else can you work out? Write down the formula you’re going to use and fill in the gaps e.g. on the first line you could start with: V = I x R or Q = I x t Once you’ve filled in those columns you should able to complete the rest of the gaps in that set using other triangles. Good luck!
