This activity introduces resistors, describing their effect in reducing current in a circuit, and explains the use of rheostats to control current. Students are expected to draw two-column tables to record their measurements, including column headings and units.
This item teaches:
- the relationship between the current and resistance in a parallel circuit
- about the use of rheostats to control current
- the relationship between the current and resistance in a series circuit
- the resistance equation: potential difference = current x resistance
- about the applications of resistors
- The pupil knows that, for a fixed supply voltage, increasing resistance in a circuit will decrease current and vice versa.
- The pupil understands the function of a rheostat.
- The pupil can produce a 2-column table with headings, units, and ordered independent variable entries and corresponding dependent variable entries.
