Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .

Why is an operational amplifier called so?
Originally such an amplifier did mathematical functions.
Why does an operational amplifier need a power supply?
It doesn't. You can make a differential amplifier with a single power supply.
Is operational amplifier is analog or digital?
analog device
What is the full form of OP-AMP?
operational amplifier
What are the values so that over all gain is 10 in instrumentation amplifier?
You need a divider that is 10 to 1. You could use 10 megohms in the feedback and 1 megohm in the bottom leg. Since you are probably talking about an operational amplifier, you need this in both legs.
Types of Negative feedback amplifier?
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback

What is the lm358?
The LM358 is an operational amplifier.
What are the advantages of operational amplifier 741?
It has several but one of the main ones is that it has built in frequency compensation, which its predecessor the 709 operational amplifier did not.
What does gm0 represent in a BJT amplifier circuit?
gm0 is not used in BJT amplifier circuits; it is used in JFET circuits. It is the transconductance at zero gate bias. Since the transconductance varies as the bias is varied, this gives a benchmark level at a given defined point, and other transconductances can be calculated from it as a function of the amount of negative bias on the gate. If it were linear it would be the same everywhere, but it is not.
Why are inductors not usually connected to an operational amplifier?
no
