Create a three-stage transistor level operational amplifier that consists of a differential input stage with large input resistance, a gain stage, and an output stage with low outputresistance. Use the op-amp you designed to create an inverting amplifier using negative feedback with a gain Av= -Rf / Ri.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

What precautions should you take to prevent injuries when dealing with heavy loads?

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
