Meaning and Definition
An electrode used to regulate the flow of electrons or the operation of a device, typically in an electron tube or a semiconductor device.
In electronics, an electrode to which a control signal (like a voltage or current) is applied to modulate the flow of charge between other electrodes, thus controlling the device's output.

FAQ
Frequently Asked Questions
In the context of field-effect transistors (FETs), yes, 'gate' is the specific name for the control electrode. In other devices like vacuum tubes, 'control grid' is used.
Yes, depending on the device type (e.g., NPN vs. PNP bipolar transistors, N-channel vs. P-channel FETs), the control voltage applied to the electrode can be positive, negative, or varying.
No, it is a specialised engineering term. While the concept is in every transistor, the specific phrase 'control electrode' is used mainly in technical documentation, textbooks, and research.
In electronics, a control electrode regulates operation. In electrochemistry, a 'working electrode' is where the reaction of interest occurs, a distinct and unrelated term.
An electrode used to regulate the flow of electrons or the operation of a device, typically in an electron tube or a semiconductor device.
Control electrode is usually technical in register.
Control electrode: in British English it is pronounced /kənˈtrəʊl ɪˈlɛktrəʊd/, and in American English it is pronounced /kənˈtroʊl əˈlɛktroʊd/. Tap the audio buttons above to hear it.
