Why we use the symbol ground in electronic circuits?

If I am not wrong, the power ground is the reference point in the circuit, assumed to be at 0V. It is usually the -ve terminal of the battery in case of single power supply and the mid-potential point (point where -ve of Vcc and +ve of Vee are joined) in the dual power supply. Dual supply will have three voltages, Vcc, GND(assumed 0) and -VEE..cbram said:The one which has power ground
What does the power ground do

Please don't apologize!jim hardy said:i feel almost apologetic for the diatribe
but I've seen soooo many newbie engineers struggle with "ground" that i try to disseminate the idea...
Where did the op amp ground pin go?
Did you know that there are operational amplifiers (op amps) with a ground pin? If you’re an experienced analog engineer, you probably know that, but those who haven’t worked much with older op amps might be asking themselves, “What’s a ground pin?”
Integrated circuit (IC) manufacturers used to label the ground pin, which is supposed to indicate zero volts, “GND.” Today, manufacturers like TI label the pin on new op amps “V-,” or “N/C” (negative supply and no connect). This is because GND is supposed to indicate zero volts, but an op amp never puts out exactly zero volts, making the original label confusing...
No, but an input pin named GND has been used, especially in old designs. I cannot remember which at the moment, but (as a poor substitute) the LM324 (http://www.ti.com/lit/ds/symlink/lm124-n.pdf) uses GND to designate a power dupply connection.meBigGuy said:What opamp ever had an output pin labeled ground?
I'd saymeBigGuy said:I'm referring specifically to this:
"This is because GND is supposed to indicate zero volts, but an op amp never puts out exactly zero volts, making the original label confusing"
What is he trying to say?
I think i will...I would like to hear your comments about your experience with the GND pin. Log in and drop me a line below in the comments. Let me know why you think it was there in the first place.
Grounding is necessary for electronic circuits because it provides a reference point for the flow of electric current. Without a ground connection, the circuit may experience fluctuations in voltage and can become unstable, leading to malfunctions or damage.
If an electronic circuit is not properly grounded, it may experience issues such as high voltage spikes, electric shocks, or interference from external sources. This can not only damage the circuit components but also pose a safety hazard for users.
No, not all types of ground can be used for electronic circuits. The ground used for electronic circuits must have a low resistance to allow for the dissipation of excess current. It should also be isolated from other ground connections to prevent noise interference.
Grounding prevents electric shocks by providing a path for the excess current to flow into the ground instead of passing through a person or other objects. This is especially important for electronic devices that are in contact with humans, such as laptops or smartphones.
No, not all electronic devices need to be grounded. Devices that are double-insulated or run on batteries do not require grounding. However, devices that are connected to a power source should be properly grounded to ensure their safe and efficient operation.
