Loops of a parallel circuit
I can divide a parallel circuit into a set of nested series circuits.
Loops of a parallel circuit
I can divide a parallel circuit into a set of nested series circuits.
Lesson details
Key learning points
- In a parallel circuit, each loop can be traced from one end of the battery round to the other end of the battery.
- Each loop in a parallel circuit is equivalent to a series circuit connected to the same battery.
- A parallel circuit can be divided into a number of series circuits, each connected to the ends of the same battery.
Common misconception
Pupils are often confused about how to analyse a parallel circuit.
Emphasise the need to consider each loop of a parallel circuit as if it were a single series circuit connected to the battery.
Keywords
Series circuit - An electric circuit with one complete loop, from one end of a battery round to the other end.
Battery - A component that uses a chemical reaction to make electric charge flow round a circuit.
Parallel circuit - A circuit with more than one complete loop, from one end of a battery round to the other end.
Potential difference - A more scientific term for voltage.
Equipment
Lamps, wires, 3 V batteries for class practical.
