# Infinite Analog Calculator

**Electricity and Magnetism**Level 3

An operational amplifier is an integrated circuit with wide applications in analog electronics. (Though it can also be used in digital circuits)

Ideally, its properties are:

Infinite Input Impedance

Zero Output Impedance

Infinite Voltage Gain

One interesting application of the op amp is it can perform addition and subtraction.

Given the circuit, calculate \(\frac{-V_{o}}{V_{i}}\)

NOTE: The inputs of the opamp are the + and - sign, the output is connected to the vertex of the triangle.
