change = ..............................................V [1] (ii) the maximum possible value of the potential difference across the resistor.
Write your Centre number, candidate number and name on all the work you hand in. Write in dark blue or black pen. You may use a soft pencil for any diagrams, graphs or rough working. Do not use staples, paper clips, highlighters, glue or correction fluid. DO NOT WRITE IN ANY BARCODES.
Answer all questions. You may lose marks if you do not show your working or if you do not use appropriate units.
At the end of the examination, fasten all your work securely together. The number of marks is given in brackets [ ] at the end of each question or part question.
