- What is an electrode? - Electrical Engineering Stack Exchange
It uses two electrodes to detect the presence of water Electrostimulation therapy uses electrodes (often with adhesive) A Van de Graaff generator is an electrode A ground rod is an electrode (as is the cold water pipe and building steel) It could be argued that an antenna is an electrode (although no one calls them that)
- Why cyclic voltammetry requires three electrodes?
Normally, you want the applied potential difference between working and reference electrode not to change When you use two electrode setup, as chemical reaction occurs, there is some current (faradaic) passing through reference electrode which when combined with reference electrode resistance changes the potential at which reference electrode stays, thus changing the potential differ
- operational amplifier - What is Ground Electrode in EMG? - Electrical . . .
Whether the electrode is connected to the GND node of the front-end is dictated by the front-end design, and is not any sort of an absolute requirement Yes, the common name is "ground electrode", but its purpose has nothing to do with ground Calling it a "potential equalization" electrode would be truer to its purpose
- Effect of the placement of ground electrode on ECG
For the recording on the top column, the ground electrode is placed on the leg, whereas for the bottom recording, the ground electrode is placed on the palm beside the positive electrode The recording with GND on the leg has a higher dynamic range (which might be good) but more high-frequency noise (which is bad) than the recording with GND on
- Does electrical current flow from positive to negative or negative to . . .
The answers you were given and what you were taught in school are all correct When electric current was first discovered people didn't know which way to choose and they assumed that it flows from positive to negative
- why is a GROUND electrode needed with a referential amplifier?
Interesting to know that it doesn't have to be I'm guessing that #1 - shielding is the reason in this case (signal levels are typically 20-50uv) then as the ground electrode is always attached to the patient too! (Often very close to the reference electrode for EEG ) \$\endgroup\$ –
- Chip antenna ANT161575ST-1202A1 layout question
The L-shaped trace coming from the "Radiator Electrode" pad of the ANT161575ST should not be grounded In fact, I'd consider that trace to be the antenna, and the chip itself to be mostly a matching network
- Why is the Anode positive if Anions are negative. . . ?
It is the electrode through which electric current flows into a polarized electrical device For a discharging battery, this is the negative lead This is how I connected anode anion and cathode cation during chemistry class when we were discussing batteries
