Transistor 2N2907 Pinout Features

n transistor is a PNP Bipolar transistor available in a metal can package having a high mA value of current with a low voltage of v Transistor N being is fully biased when a positive current is given to the base This transistor is having a gain value of - which shows the amplification capacity It is also used for amplification and switching When the transistor is fully biased it allows a maximum of mA current through the collector and emitter of v its called the saturation region When the base current is removed the transistor is in an off Read More

Over voltage and Under Voltage Protection System

Unexpected Changes in the power supply may become the cause of many problems in homes offices and industries nbsp Voltage up and down in the electric power has a very dangerous effect on the connected load nbsp Fluctuations of over-voltage and under-voltage nbsp protection systems are produced to control the bad effects Generally these systems are used in water pumps agriculture motors and etc We are going to discuss the different control structures like timers and compactors of the nbsp Undervoltage nbsp amp nbsp overvoltage protection system in this article What is an Over Voltages and Under Voltages When the Read More

Piezo buzzer features equivalent

In simplest terms a Piezo Buzzer is an electronic device that produces a tone alarm or sound Piezo buzzer is like tiny little speakers but unlike speakers it does not require an amplifier or other circuit to drive When voltage is applied to the piezo its size grows and shrinks and tone generates nbsp Pin configurations of Piezo buzzer Pin Number Pin Name Description recognize by the symbol or taller terminal lead Can be powered by V DC ndash recognized by a short terminal lead generally connected to the earth of the circuit Features of a Piezo buzzer some important Read More

Battery Level Indicator Using LM 3914

We are going to show you how to design a simple nbsp Battery Level Indicator nbsp Circuit nbsp using LM The battery level indicator indicates the status of the battery by a glowing LED In this circuit we have LEDs that show the level of the battery The battery nbsp level indicator circuit increases the lifetime of the battery because this circuit indicates your battery is full or overcharged or empty nbsp Battery Level Indicator Circuit using LM Circuit Diagram The circuit diagram of the battery level indicator is given below The components required list is also given below This Read More
