How to build a simple transistor circuit schematics?
In this compilation of simple transistor circuits (schematics) you will come across many small very important transistor configurations, especially designed and compiled for new budding electronic enthusiasts.
How to calculate the base resistor of a BJT?
The formula for calculating the base resistor of a BJT can be seen below: R = (Us – 0.6).Hfe / Load Current, Where R = base resistor of the transistor, Us = Source or the trigger voltage to the base resistor, Hfe = Forward current gain of the transistor.
How does a transistor work in a circuit?
This is how this circuit works if you are interested. When a transistor is ON it allows current to flow through it so that the LED above it will light up.The two capacitors C1 and C2 will alternate between being charged and discharged and thereby turning the transistors ON and OFF.
What are resistors used for in a circuit?
Resistors are basically used for controlling voltage and current in a circuit which becomes highly crucial for operating the various active, sophisticated components.
Are there any interesting hobby electronic circuit projects?
A few of the interesting and useful hobby electronic circuit diagrams already published in this blog have been selected and compiled here for quick reference and understanding. The complete circuit schematic for the proposed Magnetic Field Detector presents itself in the following figure.
How are transistors used in modern digital electronics?
One of the best features of transistors that enables modern digital electronics is that a transistor can act like a switch. When you turn on the light switch in your home, you do a little mechanical work with your hands that allows electricity to flow through your light bulbs.
How many transistors are used in a Darlington circuit?
The circuit provides good load regulation, its maximum current being not more than 500mA, sufficient for most applications. This circuit is built around just two transistors as the main active components. The configuration is in the form of a standard Darlington pair, which increases its current amplification capacity hugely.
