👉🏻Ohm's law: This is the fundamental relationship between electric current, voltage, and resistance. It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to its resistance. Mathematically, it is expressed as I = V/R, where I is the current in amperes, V is the voltage in vo…

Showing the 12 most recent of 20 posts we hold for @BasicElectronics. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
