It also describes their working‚ application and uses. I. INTRODUCTION Simple stand alone electronic circuits can be made to repeatedly flash a light or play a musical note‚ but in order for an electronic circuit or system to perform any useful task or function
Premium Resistor
is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. If only two terminals are used‚ one end and the wiper‚ it acts as a variable resistor or rheostat. A potentiometer measuring instrument is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle‚ hence its name. German inventor Johann Poggendorff designed the first potentiometer in 1843 RESISTORS A resistor is a component of

SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification
