Components with changing resistance

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

  • Measure pairs of readings, of current through a component and p.d. across it.
  • Use pairs of values, read from an IV-graph, to calculate resistance of a component for a given p.d....

Sensing circuits

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

  • Use the addition rule for p.d. in a series circuit to calculate the p.d. across components.
  • Use the ratio rule for p.d. in a series circuit to calculate the p.d. across components...
