    The Electric current question probes the pupils' ideas about what is actually happening (unseen) inside the wires of the circuit. The best description of the electric current in the circuit is that there is an electric current in the wires connecting battery to bulb and the same current in the bulb and the battery.

    The Electric charge question probes whether pupils think of charge as flowing out of the battery into an empty wire, or picture (correctly) the wire already full of charge that the battery sets in motion.
