Do you mean "What is a sensor in a circuit?" have a look at the link to the Wikipedia entry,
I guess Electric Circuit....
an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit
In a series circuit, the potential voltage across the circuit components adds up to the total voltage of the circuit.
If one bulb in a series circuit goes out, then current can't flow anywherein the circuit. A circuit in which current can't flow is an open circuit.
A circuit diagram is a visual representation of an electrical circuit using symbols to show components and connections. In a closed circuit, the electrical current can flow continuously through a complete path without interruption. The circuit diagram helps to understand how the components in a closed circuit are connected and how the current flows.
