Basic Electrical Symbols

Let's go over some sample electrical symbols and what they represent.

Ground or Earth

A ground symbol (IEC symbol 5017) identifies a ground terminal. It can be used for a zero potential reference point from where current is measured. It is also for electrical shock protection. There are a few different ground symbols. The one we're showing here is "Earth", but there's also a Chassis and Digital/Common ground with slight variations to this symbol.

Resistor

A resistor reduces current flow. In a schematic, this is represented with a few zig zag squiggles. We're showing the US/Japan version of this symbol (IEEE). The UK uses a simple box over a straight line (IEC). There are also symbols for variable and adjustable resistors as well as thermal and preset resistors.

Switch

Disconnects the current when open. We're showing a simple SPST (single-pole single-throw) toggle switch, but there are variations for SPDT, pushbutton, dip, relay, and more. For a complete list of switch symbols, check out SmartDraw's electrical symbol library.

Capacitor

A capacitor symbol shows two terminals running into plates. The curved plate indicates that the capacitor is polarized. The curved side has lower voltage. A small plus sign can be added to the straight side indicated the positive pin.

Fuse

A fuse protects electrical circuits by stopping the flow of current when the intensity of current exceed a set value. It does this by melting a special wire.

Antenna

Marks a device, rod, or wire designed to capture radio and electromagnetic waves into electrical signals and vice versa.

Inductor

An inductor is also called a coil or reactor. The coils store energy in a magnetic field or flux. An inductor symbol looks like a series of looped coils.

Transformer

A transformer is two or more coils coupled by magnetic induction. It helps keep the frequency and reduce tension in an AC circuit.

Motor

A motor is a device that can transform electric energy into mechanical energy.

Source

Represents the power source for your electronics. This symbol represent a direct current (DC). To represent AC current, you'd replace the plus and minus sign with a wave.

Battery

Batteries are represented on a schematic with a pair of disproportionate, parallel lines. The number of lines indicates the number of series cells in the battery.

Diode

A diode only allows current to flow in one direction. It's always polarized with an anode (A, positive) and cathode side (C, negative).

Diode LED

A diode LED is a standard diode symbol with two small arrows showing the emission of light.

Answer 2

An explanation of electrical symbols of commonly used components is shown below.

Explanation:

Ground or Earth -

• A ground terminal is designated by the ground symbol (IEC symbol 5017). It can be utilized as a current measurement reference point with a zero potential.
• Additionally, it protects against electrical shock. Several different ground symbols exist.

• The one we're displaying here is "Earth," however there are also options for a chassis and a digital/common ground.

Resistor -

• Current flow is decreased by resistors.
• This is shown schematically by a few zigzag squiggles.
• We are displaying this symbol in its US/Japan variant (IEEE).
• In the UK, a basic box is preferred to a straight line (IEC).
• Along with thermal and preset resistors, symbols are also used for variable and movable resistors.

Switch -

• when open, cuts off the current.
• The toggle switch we're demonstrating is a straightforward SPST (single-pole single-throw) switch, but there are also SPDT, pushbutton, dip, relay, and other variants.
• Visit the electrical symbol library in SmartDraw for a complete list of switch symbols.

Capacitor -

• Two terminals connecting to plates are displayed as capacitor symbols.
• The capacitor is polarised, as shown by the bent plate.
• The voltage is lower on the curved side.
• To indicate the positive pin, a tiny + symbol might be put to the straight side.

Fuse -

• When the intensity of the current exceeds a predetermined threshold, a fuse shuts off the flow of electricity, protecting electrical circuits.
• This is accomplished by melting a unique wire.

Antenna -

• Identifies a tool, wire, or rod that can convert radio and electromagnetic waves into electrical impulses and the other way around.

Inductor -

• Coil and reactor are other names for an inductor. A magnetic field or flux is used to store energy in the coils.
• A collection of looping coils is what an inductor symbol looks like.

Transformer -

• Two or more coils connected by magnetic induction make up a transformer.
• It assists in maintaining frequency and lowering tension in an AC circuit.

Motor -

• An object that can convert electrical energy into mechanical energy is a motor.

Source -

• Exemplifies the source of power for your electronics.
• Direct current is represented by this symbol (DC).
• The plus and negative signs would be swapped out for a wave to indicate AC current.

Battery -

• A pair of disproportionate, parallel lines serve as the schematic representation of batteries.
• The quantity of lines indicates how many series cells are present in the battery.

Diode -

• A diode only enables one direction of current flow. It is always polarised, with a positive anode (A) and a negative cathode side (C, negative).

LED diode -

• A diode LED is represented by a typical diode symbol with two tiny arrows indicating light emission.
