Operational Amplifiers

Q1: The open-loop voltage gain (Aol) of an op-amp is the

A external voltage gain the device is capable of

B internal voltage gain the device is capable of

C most controlled parameter

D same as Acl

ANS:B - internal voltage gain the device is capable of

In other words open loop voltage of an op amp is the maximum gain gain that the op amp can give (i.e. If the parameters are unchanged since once an op amp is manufactured it can not changed it is also called internal voltage gain) and using a feedback resistor loop we decrease our gain.
