Earthed line in Split power supply in op-amp

AI Thread Summary
The discussion centers on the role of the earthed line in a split power supply for operational amplifiers (op-amps), particularly regarding its function beyond shock prevention. Participants seek clarification on how the earthed line maintains zero potential between two power sources in the op-amp circuit. A request is made for an equivalent schematic diagram of a common op-amp, such as the LM741, to facilitate a more in-depth discussion. The conversation emphasizes the importance of understanding grounding in electrical engineering applications. Overall, the topic highlights the significance of the earthed line in ensuring proper operation of op-amps.

What is the work of the earthed line with zero potential between two power sources in the op-amp.

What is the normal function of Earth wire except for preventing shock?

@Miraj -- can you post an equivalent schematic diagram of a typical opamp, like an LM741 or similar? That will make it easier for us to discuss your question.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
