Answer / kishor mahale

opamp has two input and one output. it compare or
differentiate two input and gives respective output of input.

Answer / vinay kr

As it has 2 inputs & 1 output & o/p is wrt 2-i/ps,now a
block with minimum(sufficient) area producing 1-o/p
corresponding to 2 i/ps must be triangle with o/p at its
vertex .It shows above picture with min area as triange

Answer / ang

the opamp has 2 inputs and only one output, so its like a
device which accepts 2 datas and give one data as output.
the best geometrical figure which can describe it is a
triangle : 2 i/p s at the lower side and o/p node at the
opposite vertex

Answer / josh

because it has 2 i/p terminals having high i/p impedence
which can b showm in for of two terminals ......compared to
its o/p impedence which in ideal case is considered zero
appox.......... so shape covention is triangular

Answer / brajesh kumar sah

Because its having two input and one output , the output are the difference of the two input that why its make triangular shape.

Answer / pra

The shape of op-amp symbol is triangular because it shows the arrow,and this arrow is indicating the power transfer from input of an op-amp to the output.

Answer / anushareddy

Because to transfer the power from input terminal to output

Answer / bablu

it gives the direction of signal flow

Answer / veena

the direction of flow of current is shown in a particular
direction. and it is obviously a diferential amplifier
having two inputs and a output

Answer / harshita

because the triangular shape is like an arrow which shows
direction of current flow from input to output
