since gain is simply -Rf/Ri and is 1+Rf/Ri in case of non inverting
Inverting and non-inverting modes refer to the two primary configurations of an operational amplifier (op-amp). In the inverting mode, the input signal is applied to the inverting terminal (negative input), resulting in an output that is 180 degrees out of phase with the input, with a gain determined by external resistors. Conversely, in the non-inverting mode, the input signal is applied to the non-inverting terminal (positive input), producing an output that is in phase with the input and has a gain greater than one, also determined by external resistors. Both configurations leverage the op-amp's ability to amplify voltage signals while providing different phase relationships and gain characteristics.
gain in an op-amp is the output voltage divided by input voltage. for the inverting amplifier , gain(Av)=-(Rf/Ri) ,where Rf => resistance of the feedback path & Ri=> inverting input terminal resistance for the non-inverting amplifier , gain(Av)=(1+(Rf/Ri)) , where Rf => same & Ri=> non inverting input terminal resisance
I should expect a real-world op-amp to have 5connections:-- the inverting signal input-- the non-inverting signal input-- the signal output-- the power supply input-- the ground connection.
There is no such thing as an inverting or a non-inverting op amp.All op amps have both an inverting input and a non-inverting input. Their operation is such that the output will go to whatever value is required to make both inputs be the same. This implies feedback from output to inverting input.
it is when the feed back resistance is been connected between the inverting input and the out put
positive in inverting and negative in non inverting
When the feedback of the output terminal of an Op-Amp is given to the non-inverting terminal [pin 3 for IC-741] of that Op-Amp , then , that circuit is called non-inverting amplifier using Op-Amp. This circuit is called non-inverting because the output signal of this circuit is in phase with the input signal.
It is not true. The non-inverting summing amplifier is used all the time. It is an excellent Analog Signal Processing circuit. As an example, the bipolar to unipolar converter can be designed with a non-inverting summing amplifier.See Related links below for more information.

The output voltage of a opamp when the input of inverting and non inverting terminals are grounded
I should expect a real-world op-amp to have 5connections:-- the inverting signal input-- the non-inverting signal input-- the signal output-- the power supply input-- the ground connection.
if non inverting terminal is grounded and input is applied to inverting terminal then as the difference in input voltage should be ideally zero the potential at inverting terminal is also assumed to be zero

Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
To increase the current drive capability of a previous stage (with gain =1). To preserve the phase of the signal when used in summing circuits etc.
No, they only use the power drawn from the service. The fact that is is 220 amp or 110 amp makes no difference. It is the load that is applied that determines the amount used.
