What is Reading: Definition and 635 Discussions

Reading is the process of taking in the sense or meaning of letters, symbols, etc., especially by sight or touch.For educators and researchers, reading is a multifaceted process involving such areas as word recognition, orthography (spelling), alphabetics, phonics, phonemic awareness, vocabulary, comprehension, fluency, and motivation.Other types of reading and writing, such as pictograms (e.g., a hazard symbol and an emoji), are not based on speech based writing systems. The common link is the interpretation of symbols to extract the meaning from the visual notations or tactile signals (as in the case of Braille).

    Reading a signal off of one wire?

    When I put an o-scope probe into my (120VAC) wall socket, with no ground (reference) attached, just a single wire, I get a perfect 60 Hz sine wave, with about 35Vrms magnitude. When I plug the o-scope probe into the socket with the ground attached appropriately to the return of the same...

    Where Does the Rest of the Voltage Go in a Rectifier?

    When we take down voltmeter readings from the terminals of a Rectifier (rated 12V), we get the voltmeter reading as 4.5V. Does that mean the rest of the voltage is lost in the form of voltage drop? or is it because of the current drawn by the load? I would be glad if someone could please post...
