In electrical and electronics engineering, a periodic vibration in voltage or current is known as oscillation or electronic oscillation. Oscillation in electronics can also defined as a process of repeating cyclic vibrations of voltage or current about its equilibrium value in time.The number of times the cycle repeats per second is known as the frequency of the oscillation and is measured in cycles per seconds or Hertz (Hz).Some energy at a specific frequency is required to produce the oscillations, this requirement is fulfilled with the help of an electronic circuit called oscillator. An oscillator is an electronic circuit which is ... Read More

The electrical power produced at the generating stations is transmitted to the points of utilization which is achieved with the help of grids (an interconnected network for electricity transmission and distribution from producers to the consumers). Based on the devices used and their functionality, the electric power grids are classified into two categories viz. −Conventional grid (or traditional grid)Smart gridMany issues contribute to the incapability of conventional grid to competently meet the demand for consistent power supply. In order to resolving these problems, the smart grids are developed which is infused with the intelligent sensors and controllers, automated switches and ... Read More

An electrical machine that is used for the conversion of electrical energy into mechanical energy is known as electric motor. Based on the type of electric supply input, the electric motors are of two types − AC motor and DC motor. An AC motor is the one which takes alternating current supply as input and converts it into mechanical energy while the DC motors takes DC supply as input.Present day advancements in the motor technology allows the use of DC motors in several applications from small toys to larger industrial machinery. DC motors come in two variants viz. Brushed DC ... Read More
