A transistor need both adequate current and voltage to be activated right? And does it get damaged by connecting in wrong terminal?
hei said:My knowledge about transistor is too low, i have no idea what is FET or MOSFET yet, and i found this http://www.williamson-labs.com/images/e-spring.gif animation interesting, what does the spring mean? Does it mean the resistance increase when it is stretched longer?

I am trying to understand how the V to I convertor work. In that example, I a, not very clear what does this I to V convertor do in this circuit, why would we want to change the I back to V as we want to change the V to I ?
A transistor works by using the movement of electrons to amplify electrical signals. It is made up of three layers of material, namely the emitter, base, and collector. When an electrical signal is applied to the base layer, it causes a flow of electrons from the emitter to the collector, which amplifies the signal.
The base-emitter voltage is a crucial factor in determining the behavior of a transistor. It controls the flow of electrons from the emitter to the collector. By varying the base-emitter voltage, we can control the amplification of the electrical signal passing through the transistor.
BJTs and FETs are two types of transistors that work differently. In a BJT, the flow of electrons is controlled by the base-emitter voltage, while in an FET, it is controlled by the voltage applied to the gate. Additionally, BJTs use both electrons and holes to carry current, while FETs only use electrons.
A transistor can also function as a switch by controlling the flow of electrons from the collector to the emitter. When a voltage is applied to the base, it allows the current to flow from the collector to the emitter, turning the transistor "on." When the voltage is removed, the current stops, and the transistor is "off."
Transistors are used in a wide range of electronic devices, including computers, televisions, radios, and smartphones. They are also used in amplifiers, which are essential components in sound systems. In addition, transistors are used in digital logic circuits, which are the building blocks of modern digital technology.
