- What is an electrode? - Electrical Engineering Stack Exchange
3 According to wiki, an electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e g a semiconductor, an electrolyte or a vacuum) Examples of electrodes are the cathode and anode
- Why cyclic voltammetry requires three electrodes?
Why do you need both a reference electrode and a counter electrode? Why measuring the current between the reference electrode and the working electrode is not enough? Three-electrode setup: (1) working electrode; (2) auxiliary electrode; (3) reference electrode
- How does a driven right leg work? - Electrical Engineering Stack Exchange
The most common and effective use of the third electrode is to connect it to a driven-right-leg circuit [2], [3] This circuit overcomes both of the problems listed above It reduces the effective electrode resistance by several orders of magnitude, and it allows only a safe amount of current to flow through the third electrode
- Capacitance displacement probe guard ring circuitry
Simply connecting the sensing electrode to the guard ring would accomplish this, but it wouldn't work as the edge effects at the guard ring would be included in the measurement, defeating the entire purpose of the guard ring
- How do I connect a female EEG electrode to a breadboard?
1 Electrode output end: EEG electrode: I'm trying to connect the output of EEG electrodes to a breadboard as input How do I connect the electrode to the breadboard? Usual jumper wires don't seem to fit and adding normal wires and soldering them isn't possible
- Why does only the tip of the electrode melt when arc welding?
The negative electrode is connected to the torch The positive electrode is connected to the work piece to be welded An arc is created by a circuit in the power supply called an arc starter which produces a high voltage, high frequency pulse between the tungsten tip and the work piece
- What if the ground in EEG EMG has high impedance
Draw a schematic, or post a diagram Be aware that not everybody is aware of the technicalities or jargon of EEG measurement Show between which pairs of electrodes you are taking measurements I am not clear how this 'ground' electrode is being used, whether as a reference in one or more leads, or is it being driven to control common mode, or something else?
- sensor - How to do water detection with a single electrode . . .
Is the electrode imposed? If not, you can easily have a single electrode in a "mechanical" sens (ie a single stick) but with 2 distinct electrodes from an electric poitn of view A very simple solution would be a small strip cut out of a stripline prototyping PCB where you keep just 2 parallel copper lines Of course, if it is for long term use, you might want some material less subject to
