See it on the paper →Comprehensive responses • Many candidates calculated the value of 72 and included the units of C. Limited responses • Some candidates did not convert minutes to seconds giving a value of 1.2 instead of 72. • A few candidates did not include the units or included alternative units including A/S, V or Ohms instead of C.

Comprehensive responses • Many candidates described direct and alternating current in terms of direction of travel of the current. Limited responses • Some candidates described alternating current as changing instead of changing direction. • Some candidates referred to voltage instead of current. • Some candidates omitted this question.

This was one of the more demanding questions for candidates. Many did not know the relationship and so tried various manipulations of the figures. Quite a few started down the route of calculating power but then divided by time instead of multiplying. Some gained the mark for the unit, which was awarded independently of the calculation. Some candidates did show their working which allowed them to...
