Q. What is Open-loop voltage gain?
The op amp amplifies the difference vd between the voltage on the noninverting (+) terminal and the inverting (-) terminal; see Figure. The term "open loop" implies that there is no external feedback connection between the output and either of the inputs. A is defined as the ratio of the change in output voltage to the change in differential input voltage, usually for a load resistance of no less than 2k. A typical value for A is 2 × 105.
Connect the two signals used in section 2 above to the "Multiplier" module. Make sure that you record the amplitude of each signal. Observe and record the resultant waveform in
Single Phase Meters Single phase meters are commonly rated for 240 V AC supply; the current ratings are 5/10, 10/20, 2.5/10 or 5/20 A or are for direct connection to the mains
