Question

What symbol is used for drawing connecting wires in a circuit diagram?
A. lines
B. dotted lines
C. cross
D. circle

Answer 1

Hint:Different symbols or notations are used in physics to represent different quantities. The denotations make it easier to represent the quantities. It's worth noting that some physics symbols (like "d" for distance) are very relatable, while others (like "c" for the speed of light) are not.

Complete answer:
Electrical currents need a medium to travel from one point on a circuit to another, and connecting wires provide that. In the case of computers, wires are embedded in circuit boards to carry electrical pulses. Because copper is inexpensive and electrically conductive, most wires in computers and electronic components are made of copper or aluminum.

An electrical circuit is represented graphically in a circuit diagram (electrical diagram, elementary diagram, electronic schematic). A pictorial circuit diagram uses simple images of components, whereas a schematic diagram uses standardized symbolic representations to show the circuit's components and interconnections.

A circuit diagram, unlike a block diagram or a layout diagram, shows the actual electrical connections. The term artwork, layout, physical design, or wiring diagram refers to a drawing that depicts the physical arrangement of wires and the components they connect. Electrical and electronic circuit diagrams are used for design (circuit design), construction (such as PCB layout), and equipment.Wires are represented in the circuit by lines.

Hence, option A is the right answer.

Note:Circuit diagrams are pictures with symbols that have changed over time and differed from country to country, but are now largely international standardized. Simple components frequently had symbols that represented some aspect of the device's physical construction.
