Electrical connection to an insulator to carry current

AI Thread Summary
A project involving a Faraday cup is discussed, where a metallic cylinder with an insulator electrode at the bottom captures ions. The main concern is how to establish an electrical connection from the insulator electrode to an amplifier, given that insulators do not conduct electricity. Questions arise about whether the insulator can provide a charge for the wire to carry and how electrons can reach the surface of the insulator. The discussion emphasizes the challenge of connecting a non-conductive material in a way that allows for current flow. Understanding the properties of insulators and potential methods for creating a connection is crucial for the project's success.

I am working on a project that uses a Faraday cup. Its consists of a metallic cylinder(pipe like) with an electrode at the bottom.The ions enter the cylinder and hit the electrode.The resulting current is carried away from the electrode to an amplifier by a wire .The electrode that i am using is an insulator. So how do i provide the electrical connection.the electrode being an insulator,will it give any charge for the wire to carry

How can an electrode not conduct? Electrons need to get to its surface don't they? (By definition)
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
