The discussion centers around difficulties in oscillating a sine wave from a "bubba" oscillator using pSpice. A key point raised is the importance of correctly connecting power supply pins, particularly noting that TL084 and LM348 op-amps use pin 4 for Vcc, which differs from typical configurations. The user confirms that their connections are correct, prompting a question about the difference between Vcc and Vee. The conversation emphasizes troubleshooting power supply connections as a critical step in resolving the issue. Proper understanding of op-amp pin configurations is essential for successful circuit operation.

Cant oscillate sine wave from "bubba" oscillator
hey
i can't oscillate sine wave from "bubba" oscillator using pSpice.
see the following attachment.
can u please help me?
Make sure that you have your power supply pins right. TL084's and LM348's use pin 4 as Vcc, which is a little confusing when you used to pin 4 being used for Vee on all of the dual op amp parts.

What is the diffrenace between Vcc and Vee?
the pins are proper connected as u can see in the attachment.
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?
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...
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...
