AI Thread Summary
The discussion centers on understanding J-K flip flops and their timing diagrams. The user seeks clarification on the meanings of "set" and "reset," specifically how J = 1, K = 0 sets the flip-flop (making Q = 1) and J = 0, K = 1 resets it (making Q = 0). They express confusion regarding the timing diagram and the role of the clock in these operations. Ultimately, the user concludes that they have grasped the concept after further reflection. The conversation highlights the importance of timing diagrams in comprehending flip-flop behavior.

I'm trying to understand how the J-K flip flop works and how to draw the timing diagrams. I was reading about it on wikipedia and was wondering if someone could explain this to me: "Specifically, the combination J = 1, K = 0 is a command to set the flip-flop; the combination J = 0, K = 1 is a command to reset the flip-flop." What do they mean by set and reset? Does set mean the balue of Q goes to 1 and reset means Q goes to 0 or something and how does the clock affect it? I did look at the timing diagram provided and it was confusing. I understood the toggling part and table but not anything else. Thank you.

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...
