A proportional controller with a gain of KC is used to control a first order process. The offset will increase if

The basic principle involved in the measurement of temperature by thermocouple is

The time constant of a first order process with resistance R & capacitance C is 

A sinusoidal variation in the input passing through a linear first order system

Gain margin is equal to the 

The error required to move the value from fully closed to fully open is termed as
