AI Thread Summary
Tighter twisting in twisted pair cables enhances transmission rates by improving the coupling between the wires, which reduces electromagnetic (EM) radiation loss. This design minimizes energy escape along the cable's surface, allowing for higher frequencies to be transmitted over longer distances. Additionally, tighter twists contribute to better common mode rejection, further enhancing signal integrity. Overall, the twisting technique is crucial for optimizing performance in data transmission applications. Understanding these principles is essential for effective cable design and usage.

Why is that in twisted pair cable, the tighter the twisting, the higher the supported transmission rate?


Thankyou

The tighter the twist, the better the coupling between the two wires, the less the EM escape out along the surface so less energy is lost from radiation along the way so higher frequencies can be carry for longer distance.
 
I totally forgot the common mode rejection part! Sorry.
 

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...

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 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
