It is required to connect a transducer having an open-circuit voltage of 1 V and a source resistance of 1 MΩ to a load of 1-kΩ resistance. Find the load voltage if the connection is done (a) directly and (b) through a unity-gain voltage follower.(a) 1 μV and 1 mV respectively(b) 1 mV and 1 V respectively(c) 0.1 μV and 0.1 mV respectively(d) 0.1 mV and 0.1 V respectivelyI got this question in semester exam.My doubt stems from The Non Inverting Configuration topic in chapter Operational Amplifiers of Electronic Devices & Circuits

Answer»

Correct choice is (B) 1 mV and 1 V respectively

The best I can explain: When a unity GAIN follower is USES then input signal is equal to OUTPUT signal. When connected directly, output signal is given by 1 X 1kΩ/1MΩ or 1mV.
