It is an amplifier that has no gain or a gain of one mainly used for isolation .
The (Class C, Common Collector) Emitter Follower is used to amplify the available current from a voltage driving circuit that might be disturbed by the load impedance. If the actual voltage value is important, the emitter follower is often teamed up with an opamp which sets the emitter voltage based on the input voltage.
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.
A: Any offset whether is voltage or current is an output error to contend with.
In a voltage follower, voltage gain is 1, with an offset of VB-E, and current gain is hFe, limited, of course, by the available current in the supply and by the rating of the transistor.

The output voltage of a opamp when the input of inverting and non inverting terminals are grounded

A: Any offset whether is voltage or current is an output error to contend with.
The voltage gain of an emitter follower is theoretically 1. In practice, due to losses, it is marginally less than one.
same as the given input..
In a voltage follower, voltage gain is 1, with an offset of VB-E, and current gain is hFe, limited, of course, by the available current in the supply and by the rating of the transistor.
Supply voltage , temperature , frequency are factors that effect the electrical parameters of opamp
