When should I use a transistor?
One of the most common uses for transistors in an electronic circuit is as simple switches. In short, a transistor conducts current across the collector-emitter path only when a voltage is applied to the base. When no base voltage is present, theswitch is off. When base voltage is present, the switch is on.
What is the main purpose of transistor?
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
What is the primary purpose of transistor?
Transistor, semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits, or “microchips,” which often contain billions of these minuscule devices etched into their shiny surfaces.
What is fuse example?
When you overload the circuit in your house by turning on too many different appliances at once and your power to the appliances you are using shuts off, the electrical device that tripped and caused the power to stop to the overloaded circuit is an example of a fuse.
How is a simple electronic fuse circuit used?
Simple electronic fuse circuit. This is simple electronic fuse circuit. It can be used to replace conventional fuses. Because it’s comfortable not need to replace the fuse every time the power too over. This circuit use transistors so simple and low cost. The Fuse is a type of electrical equipment to the poor.
Why are transistors used in a simple circuit?
This circuit use transistors so simple and low cost. The Fuse is a type of electrical equipment to the poor. Because it sacrifices itself. To protect the safety devices in the circuit.
How to cut the current of a fuse?
The current of fuse that you want to cut off circuits, can easily set easily from changing R3 which is a current detector. When we use Ohm’s law, which circuit will cut current when voltage drop across R3 is 0.6 volts. Based this condition, we can find the right resistor with the following formula. R3 = 0.6 …. (1)
Why are fuses so important to electrical engineering?
Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity, and response times, depending on the application.
