Frequently asked questions
A touch sensor Switching is a type of device that captures and records physical touch or embrace on a device and object. It enables a device or object to detect touch or proximity. typically by a human user or operator System.
A voltage or current applied to 1 pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output terminals) power can be higher than the controlling (input terminals) power, a transistor can amplify a signal.
BC547 is an NPN bipolar junction transistor. A transistor stands for transfer of resistance and is commonly used to amplify current Flow. A small current at its base controls a larger current flow at collector & emitter terminals.
The BC547 is a general-purpose BJT NPN transistor mostly used in electronics and educational electronics projects. Besides these uses it can also be used in commercial circuits Diagram.
A BC547 transistor can be used as a solid-state switch. If the transistor is operated in the saturation region then it acts as a closed switch and when it is operated in the cut-off region then it behaves as an open switch.
