Question

A straight line represents which electric component
A) load
B) resistor
C) conducting wire
D) cell

Answer 1

In a schematic design of an electrical or electronic circuit, an electronic symbol is a pictogram used to represent different electrical and electronic equipment or functions, such as cables, batteries, resistors, and transistors. These symbols are now generally standardised globally, however historic traditions may differ from country to country or engineering discipline to engineering field.

Complete Step By Step Answer:
A circuit diagram is a depiction of an electrical circuit in graphical form. A pictorial circuit diagram utilises basic pictures of components, whereas a schematic diagram uses standardised symbolic representations to show the circuit's components and interconnections. The actual arrangements in the final device may differ from how the interconnections between circuit components are shown in the schematic diagram. A circuit diagram, unlike a block diagram or a layout diagram, depicts the actual electrical connections. Layout, physical design, or wiring diagram is a drawing that depicts the physical arrangement of cables and the components they link.
Circuit diagrams are drawings with symbols that have changed through time and vary from country to country, but are now mostly worldwide standardised. Simple components frequently featured symbols that represented some aspect of the device's physical structure. The symbol for a resistor, for example, dates back to when the component was built out of a long length of wire wrapped in such a way that it didn't cause inductance, which would have rendered it a coil.

The straight line represents a conducting wire.

hence option C is correct.

Note:
The connections between leads used to be simple line crossings. The connection of two intersecting wires was represented by a crossing of wires with a "dot" or "blob" to signify a link before the introduction of computerised drafting. Simultaneously, the crossover was simplified to be the same as before, but without the "dot."
