Question:
What is external circuit
Answer:
- A circuit usually contains a power Source, which is the source of electrons and a Load, which is the electrical appliance, like a bulb, needing electricity to run. A simple circuit is depicted above.
- A switch or key in the circuit is used to make or break the circuit to start or stop current flow.
- The diagram representing an electric circuit is called as a circuit diagram.
- The electric circuit demonstrated by the combination of battery, light bulb and wires consists of two parts – external circuit and internal circuit
- Suppose the internal electrolyte part of the attached battery is illustrated in a diagram, then it becomes an internal circuit
- However, if the power source is shown as it is, with positive and negative terminals alone, then it is an external circuit. The above represented circuit diagram is a external circuit.
