AI Thread Summary
Circuit diagrams and wiring diagrams serve different purposes in electrical design. Circuit diagrams illustrate the electrical components and their connections, focusing on the functionality of the circuit, while wiring diagrams provide a visual representation of the physical layout and connections between components. Wiring diagrams may show connectors and their pin configurations, often used in assembly contexts where detailed circuit information is unnecessary. In complex devices, wiring may be simplified with numbered connections rather than individual wires. The discussion highlights the importance of clarity in wiring diagrams, especially when connecting components like connectors and ensuring proper grounding.

What is the difference between a circuit diagram and a wiring diagram.

And while your at it can anyone explain the difference between diagram that routes fibers/ connections to from a battery to a lamp for example as opposed to the alternate... one that routes to the connector on the battery and the connector on the lamp?

I have noticed wiring diagrams that only show connectors and those connections and others that show a complete system. Comments?

People who build equipment in assembly lines have no need for, nor any understanding of, circuit diagrams. They are paid for assembling the equipment, and wiring it up. A circuit diagram would only confuse them. The people I knew in Wiring and Assembly at HP in the mid-1950s didn't care whether a wire was connected to a (vacuum tube) grid or a plate.

A wiring diagram is a pictorial representation of a circuit diagram.

Usually, the active devices, like transistors and ICs, are shown as they look with the pin connections etc shown in a real sequence. The internal functions of the devices are not shown.

Sometimes a wiring harness is shown where it connects to a junction connector. This is typically done for auto electrical work where the numbers on the connector have to match the colors of the wires. What they actually do is not obvious

Some devices, like computers, VCRs and TV sets have such complex wiring that the individual wires are not shown but they are numbered and you have to look for the same number on a different part of the circuit diagram. Unless this is well done, this system can become a nighmare.
 
thanks so much for the responses. I am creating wiring diagrams that connect from connectors to connectors. What would that be called?
 
I have referred to cable connector-to-connector wiring diagrams as cable connector pin-out diagrams. It usually includes a table showing which pin on one connector is connector to which pin on the other. Don't forget to show the connector shell grounds (to cable external shield).

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
