Calculations for AQA Physics Electricity. This uses the BUG and ISSR techniques to guide students through the question and maximise their marks. Students are given the need to know information before introducing the equation and how to use it.
BUG = ***B***ox the command word; ***U***nderline key information and ***G***o through it twice
ISSR = Identify the equation needed and what you are given in the question; Substitute the values into the equation; Simplify the numbers if possible and Rearrange if needed.
This allows students to meet the new criteria of having to show their working for calculations to get all the marks.
Equations covered are:
- E = QV
- Q= It
- V = IR
- P = I2R
- P = IV
- E = Pt
