A straight line
is used to represent a connecting wire between any two components of the circuit. An electrical device that offers resistance to the flow of charge is generically referred to as a resistor and is represented by a zigzag line.
What does a wire symbolize?
Wires are
used to bear mechanical loads or electricity and telecommunications signals
. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number.

Why is a wire important?
By
powering television and computers
, it keeps us in touch with the outside world, and by powering alarms and security systems, it keeps our homes and our families safe. Here in Santa Rosa, electrical wiring helps us stay cool in the heat of the summer and lights our yards to enjoy our beautiful California nights.
What is the importance of wires?
Wire and cable as
the transmission medium of the power system
is like the blood vessels of the human body; the wire and cable plays the role of the information system as the nerves of the human body; the electromagnetic wires used in the windings of the motor and the instrument are more important than the heart of the …

What is a pictorial symbol?
One of the methods is to use picture symbols. The expression or illustration regarding the different information about any object or objects or activities through pictures or picture symbols is called pictorial representation or pictograph.
What is basic electrical knowledge?
In order to make sense of the Code, you must first understand basic electrical concepts such as
voltage, amperage, resistance, Ohm’s law, wattage, circuit theory
and others. … An obvious foundation for all electrical installations is a thorough knowledge of the laws that govern the operation of electricity.
What is the symbol of wire crossing without joining?
Wires crossing without joining: The wires that do not touch each other are drawn without
blobs
. The following figure shows how the separated wires are represented. Electric bulb: The electrical device which uses electricity to glow. Resistor (R): It is used to restrict the amount of current flow in the circuit.
What is the symbol of unconnected wire?

What are the general rules of wiring?
- Every installation is to be properly protected near the point of entry of supply cables by a two-pole linked main switch and a fuse unit. …
- The conductor used is to be of such a size that it may carry load current safely.
- The conductors installed are to be safe in all respects.
Which wire is used in household?
The most common type of wiring in modern homes is in the form of
nonmetallic (NM) cable
, which consists of two or more individual wires wrapped inside a protective plastic sheathing. NM cable usually contains one or more “hot” (current-carrying) wires, a neutral wire, and a ground wire.
