The Ground Problem

The Ground Problem

Different Symbols – Left-to-right – Earth Ground – Chassis Ground – Signal Ground

Today I was searching about how to breadboard on MultiSim, found many tutorials on the topic, but in one, I found this amazing little concept, explained, once and for all……

The copy of the text is;

The Concept of a Ground
Nevertheless, this simple circuit does introduce a very powerful concept.  Notice that we did not place a ground on the breadboard and no error occurred. Hopefully, this rather subtle point help clarifies the concept of a ground: it is just a symbol on your circuit that indicates your reference node.  A circuit does not need to have an explicit ground connection to Earth (unless you are dealing with very high voltages and want to provide a safe return path). Many circuits do not have any explicit ground connection to Earth.


The circuit being referred to is a very simple circuit, I copied this after the writer explained how to convert a MultiSim Schematic into a breadboard using MultiSim, but then he realized that there is no ground connection required when designing on a breadboard.

  1. Just wrote a small article about the CON… « Status Updates of Me, Myself, I & some others…. says:

    […] CONCEPT of GROUND, okay, I didn’t wrote it, just copied it… but do take a look… […]

  2. It is not so the current always flow towards low potential area and ground is relatively low as compared to a positive current because it provides us 0volts which is exactly be a less thing for a thinking guy and for this reason I ground that
