Circuits Hint and Question Cards

Set of 12 cards, to help students learn/revise the basic circuit rules: how to work out current, voltage and resistance in series and parallel circuits. Some of the cards give hints, which help with the questions on the other cards. I usually give each group a set, mixed up, and ask them to answer questions A-L, with the help of the hint cards. (Note: the cards do not sort into pairs - that's not the idea.) Depending on the group, takes about 10-25 minutes.
