A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

3 Phase Step Up Transformer 240 to 480 Wiring Diagram- wiring diagram is a simplified pleasing pictorial representation of an electrical circuit.It shows the components of the circuit as simplified shapes, and the capability and signal contacts in the company of the devices.
Any wiring harness should come with an OBD II port. This is a standard port for all newer vehicles. It allows you to plug in a scan tool or laptop to "talk" with the PCM to program it further or troubleshoot codes that are being thrown. The wiring harness side is a female 16 pin J1962 type connector with two rows of 8 pins.
The conventional mechanical energy meter is based on the phenomenon of "Magnetic Induction". It has a rotating aluminium Wheel called Ferriwheel and [[wysiwyg_imageupload::]]many toothed wheels. Based on the flow of current, the Ferriwheel rotates which makes rotation of other wheels. This will be converted into corresponding measurements in the display section. Since many mechanical parts ...
DC Resistance: This can be measured directly with an ohm meter and gives you an idea of how many turns of wire the coil has. If the same gauge of wire was used for two pickups, then the pickup with fewer turns to the coil will have a lower resistance which, in general, makes for a lower output level and a brighter sound.
Main Difference between Single Phase & Three Phase Power Supply. The power generation and distribution started in mid 1880 and since then the AC power supply has been used for powering common household items, office equipment and industrial machines. The AC power exists and used in two forms i.e. it is either single phase power or three phase power supply.

2 : 1 MUX using transmission gate. 2 : 1 MUX using transmission gate : A 2:1 multiplexer is shown in Figure below. This gate selects either input A or B on the basis of the value of the control signal 'C'.When control signal C is logic low the output is equal to the input A and when control signal C is logic high the output is equal to the input B.
To overcome the high power consumption in factories and to increase the efficiency, VFD was introduced four decades ago but the circuitry was not strong enough. VFD is the short form of a Variable Frequency Drive or adjustable frequency drive. The frequency determines the motor RPM and by controlling the AC frequency the motor RPM can be controlled.
