Learning Outcomes:

1. draw circuit diagrams with power sources (cell or battery), switches, lamps, resistors (fixed and variable), fuses, ammeters and voltmeters
2. state that the current at every point in a series circuit is the same and apply the principle to new situations or to solve related problems
3. state that the sum of the potential differences in a series circuit is equal to the potential difference across the whole circuit and apply the principle to new situations or to solve related problems
4. state that the current from the source is the sum of the currents in the separate branches of a parallel circuit and apply the principle to new situations or to solve related problems
5. state that the potential difference across the separate branches of a parallel circuit is the same and apply the principle to new situations or to solve related problems
6. recall and apply the relevant relationships, including R = V/I and those for current, potential differences and resistors in series and in parallel circuits, in calculations involving a whole circuit
