Who discovered electricity ?

Electricity is a type of energy found in nature. Because electricity happens naturally, it was not invented. So, let us investigate “Who Discovered Electricity?” Many scientists found and comprehended electricity. Benjamin Franklin is credited with developing electricity. On a rainy day in 1752, Benjamin Franklin did an experiment using a kite and a key. He […]

Field Effect transistor

The Field Effect transistors (FET) is a kind of transistor that controls the flow of current in a semiconductor by using an electric field. FETs (also known as JFETs or MOSFETs) are semiconductor devices with three terminals: source, gate, and drain. FETs regulate current flow by applying a voltage to the gate, which changes the […]

Low Pass Filter : Circuit & Its Working

A low pass filter is a filter that allows low-frequency signals to pass while blocking or obstructing high-frequency ones. In other words, low-frequency signals flow through considerably easily and with less resistance, but high-frequency signals pass through much more difficultly, which is why it is a low pass filter. Low pass filters can be made […]

(PWM) Pulse Width Modulation

PWM (pulse width modulation) or PDM (pulse-duration modulation) is a technique for decreasing the average power produced by an electrical signal by splitting it up into discrete portions. The average value of voltage (and current) provided to the load is regulated by rapidly switching the supply and load switches on and off. The higher the […]

Digital Logic Gates

Digital Logic Gates :Digital electrical circuits operate on two logic levels: logic low and logic high. The voltage range corresponding to Logic Low is denoted by ‘0’. Similarly, the voltage range corresponding to Logic High is denoted as ‘1’. A logic gate is a basic digital electrical circuit with one or more inputs and a […]
