What is a Diode?
A diode is a semiconductor device that allows current to flow in one direction serving as a one-way current switch. Diodes, also called rectifiers, convert alternating current (AC) into pulsating direct current (DC). They are categorized by type, voltage, and current capacity. With polarity determined by an anode (positive) and cathode (negative), diodes typically conduct…
Front End Loader with Rake -Kinematic Assesment
Introduction: The “front-end loader with rake” mechanism is an example of a heavy equipment machine used in construction and farming. Mounted on the front is a scoop or bucket connected to the end of an articulated arm. The bucket is used to scoop up material from the ground, such as snow, dirt, or feed….
Electric Battery Explained
An electric battery is an energy storage device comprising one or more electrochemical cells. These cells have external connections used to power electrical devices. When providing power, the battery’s positive terminal serves as the cathode, while the negative terminal functions as the anode. Electrons flow through an external electric circuit to the positive terminal from…
