Work, Energy and Power

 Work

work is said to be done by a force if body is displaced due to application of force on it.
Mathematically, it is measured by the product of force along the direction of displacement and displacement.
If ፀ be the angle between the direction of force and displacement, then the component of the force along the direction of displacement is Fcosፀ .
∵ W= (Fcosፀ)S

Physical variables and transducer

unit 3 Physical Variables and transducers  Sensor Sensors are electrical devices that have the capability of sensing different physical variables. The sensor may be classified on different bases one of them is a physical quantity. Hence on the basis of a physical quantity or physical vibration involved the sensors are classified as: Resistive sensor  The input being measured is transformed into a change in resistance. examples: potentiometer, resistance thermometer, strain gauge, etc. Inductive sensor The input being measured is transformed into a change in resistance. example LVDT. Capacitive Sensor The input being measured is transformed into a change in capacitance. example: capacitive Displacement sensor. On the basis of power supply required: Active Sensor Active sensors are those which do not require an external power supply.  example: thermo-couple Passive Sensor Passive Sensors are those which require a power supply. example: Potentiometer. Physical variables and ...
