This Word document contains some schematic symbols for use in Microsoft Word, PowerPoint and Excel files for reports and presentations. If you happen to. Miscellaneous Technical is a Unicode block ranging from U+2300 to U+23FF, which contains. Symbol ⏚ (⏚) is the 'Earth Ground' symbol found on electrical or electronic manual, tag and equipment. INSERTION SYMBOL, ⎐, OPEN-CIRCUIT-OUTPUT L-TYPE SYMBOL, ⎠, RIGHT PARENTHESIS LOWER.

Electrical Symbols & Electronic Symbols WIRES Wires Represents a conductor that conducts electrical current. Also called a power line or electric line or wire. Connected Wires Represents the connection of two conductors. Dot shows the junction point. Unconnected Wires Represents two unconnected wires/conductors.

Input Bus Line Represents a bus for input or incoming data. Output Bus Line Represents a bus for output or outgoing data. Game pb launcher. Terminal Represents start or end point.

Bus Line Represents a number of conductors joined together to form a bus wire. SWITCHES Push Button (Normally Open) This switch is in ON state when the button is pressed otherwise it is in OFF state. Push Button (Normally Closed) This switch is initially in ON state. This goes to OFF state when it is released. Spst Switch Single pole single throw is abbreviated as SPST.

This acts as ON/OFF switch. Poles define the number of circuits it can be connected to and throws defines the number of positions that a pole connects. Spdt Switch Single pole double throw is abbreviated as SPDT. This switch allows the current to flow in any one of the two directions by adjusting its position.

Dpst Switch Double pole single throw is abbreviated as DPST. This switch can drive two circuits at a time. Dpdt Switch Double pole double throw is the full form of DPDT. This can connect the four circuits by changing the position.

Relay Switch This represents the relay switch. This can control the AC Loads using the DC voltage applied to the coil.

SOURCES AC Supply This represents AC supply in the circuit. DC Supply This represents the DC power supply.

It applies DC supply to the circuit. Constant Current Source The symbol represents an independent current source which delivers constant current. Controlled current Source It is a dependent current source. Usually depends on other sources (voltage or current). Controlled Voltage Source It is a dependent voltage source. Game petualangan java jar 320x240.

Usually depends on other sources (voltage or current). Single Cell Battery This provides supply to the circuit. Multi Cell Battery Combination of multiple single cell batteries or a single large cell battery.

The voltage is usually higher. Wave Generators Sinusoidal Generator Represents sine wave generator. Pulse Generator Represents pulse or square wave generator. Triangular Wave Represents triangular wave generator. GROUND SYMBOLS Ground It is equivalent to theoretical 0V and is used as zero potential reference. It is the potential of perfectly conducting earth. Signal Ground It is a reference point from which the signal is measured.

There may be several signal grounds in a circuit due to the voltage drops in a circuit. Chassis Ground It acts as a barrier between user and the circuit and prevents electric shock. RESISTOR SYMBOLS Fixed Resistor It is a device that opposes the flow of current in a circuit. These two symbols are used to represent fixed resistor. VARIABLE RESISTOR Rheostat It is a two terminal variable resistor. They are generally used to control the current in the circuit. Generally used in tuning circuits and power control applications like heaters, ovens etc Preset It is a mini variable resistor.

It is also called Trimmer Resistor or Trim Pot. The resistance is adjusted with rotary control present on top of it with the help of a screw driver. They are used to adjust the sensitivity of the circuit like temperature or light. Thermistor It is a temperature sensitive resistor. They are used in temperature sensing, current limiting circuits, over-current protection circuits etc. Varistor It is a Voltage Dependent Resistor. It has non-linear current-voltage characteristics.

Generally used in circuit protection from voltage surges and excessive transient voltages. Magneto Resistor They are also called as Magnetic Dependent Resistors (MDR).

The resistance of magneto resistor varies according to the external magnetic field strength. They are used in electronic compass, ferrous material detection, position sensors etc. LDR They are also called as Photo Resistors. The resistance of LDR varies with the intensity of the light incident on it. They are generally used in light sensing applications. Tapped resistor A wire-wound type fixed resistor with one or more terminals along its length.
