Electric Field in the rotating wire frame

AI Thread Summary
The discussion centers on a failed attempt to produce ordered nanofibers using a custom electrospinning setup with a rotating copper wireframe collector. The setup involves a 20kV transformer, where the negative terminal contacts the collector and the positive lead is submerged in a polymer solution. Although some nanofibers were produced, over 60% of the solution was wasted, indicating inefficiencies in the process. Participants are asked to provide insights on how the electric field lines function within the rotating wireframe and suggest solutions to enhance the efficiency of fiber deposition. The goal is to optimize the electrospinning process to minimize waste and improve fiber arrangement.

Hi,
Myself and my friends fabricated an equipment for electrospinning- a process used used to produce nano fibers. The objective of the work is to get ordered arrangement of nanofibers(we referred a journal). But when it was put to test, it didnt work as expected:-(
Please check out the collector setup. It is a copper wireframe which is more or less like a cylindrical parrot cage. It is capable of rotating at 20 rpm. Let me explain d process.
The-ve terminal of a 20kv transformer is made to be in contact with the area mentioned in the photo and the positive lead is dipped in a polymer solution. The solution bcomes charged and due to very high electrostatic repulsion the solution breaks into very fine droplets and elongate and deposit on the collector.
But in my case the solution did deposit as nanofibers but more than 60 percent of the solution gets wasted:(
Please suggest how the electric field lines would exist for the rotating wire frame. and kindly suggest a suitable solution to correct the problem with electrical field:-)
Thanks in advance:)

note the collector is placed at about 30 cms from syringe..
 
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...
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?'
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...
