WebOpen loop vs. closed loop systems. Open loop systems, like in figure 2, pull water from underground (groundwater) and then put water back into the ground (cooler water, with the heat taken out), using the heat in the water to warm the living space.

WebOPEN-LOOP GAIN . Unlike the ideal op amp, a practical op amp has a finite gain. The open-loop dc gain (usually referred to as AVOL) is the gain of the amplifier without the feedback loop being closed, hence the name “open-loop.” For a precision op amp this gain can be vary high, on the order of 160 dB (100 million) or more.
