    Open loop op-amp circuits aren’t very useful as electronic amplifiers because they’re so easily saturated. To make an op amp useful as an amplifier, you must use it in a feedback circuit, which reduces the gain to a more manageable amount so that input voltages that are usable (and even measurable!) can be amplified reliably.

    You need a closed path, or closed circuit, to get electric current to flow. If there’s a break anywhere in the path, you have an open circuit, and the current stops flowing — and the metal atoms in the wire quickly settle down to a peaceful, electrically neutral existence. A closed circuit allows current to […]
