What else can I help you with?
Why the output of the operational amplifier positive even if the inverting input voltage is more also?
If the output of the operational amplifier is inconsistent with the inputs, then you are operating outside of the limits of the device. You might also have experienced lockup, a characteristic where the output locks in one state, but this still stems from operating outside of limits. Make sure the inputs are always within the specified range.
Why you need operational transconductance amplifier?
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 it is unsuitable for operational-amplifier to connect in open loop?
In open loop configuration the gain of the amplifier will be infinite, which in turn produces only square wave output.
Is there electrical equipment can sum 3 dc signals to get 1 output signal?
An operational amplifier can sum an arbitrary number of signals and produce a single output signal.
What is linear op amp?
It's an op amp (operational amplifier) with a linear response, meaning that double the input means double the output.

Why a triangle symbol for an operational amplifier?
Why not? It has two inputs and one output. So a triangle that can accomidate two intputs and one output is perfect!

What is offset current?
On a differential amplifier while there is some voltage offset there is also current offset which is dependent on the value of the F/B resistance the bigger value the more offset.

How does the operational amplifier work?
The operational amplifier is a device with two inputs, and one output. One input is called non-inverting, while the other is called inverting. Sometimes, there are two outputs, in which case one is also non-inverting and the other inverting. Within the limits of the design of the operational amplifier and its circuit, the output will assume whatever state is necessary to make the two inputs equal to each other. The output goes in the same direction as the non-inverting input, or in the opposite direction as the inverting input. Note that for the operational amplifer to work correctly, there needs to be some kind of feedback loop, usually from output to inverting input (we call this negative feedback), so that the output can track one of the two inputs in the ratio of the bridge that is setup in the circuit design.

Why is an operational amplifier called so?
Originally such an amplifier did mathematical functions.
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.
