Example how to determine effective resistance of a parallel circuit:
- When resistors are connected in parallel, the total resistance becomes smaller compare to series circuit.
- Thus, a higher current will flow to the smaller effective resistance and produce a brighter bulb in parallel circuit.
Advantages of using parallel circuit:
- If one of the electrical appliance does not function, the other electrical appliances still can be used.
- Additional electrical appliances can be connected in parallel with the existing appliance without the need for more voltage.
