![]() ![]() This voltage generates an electric field within the device, so by controlling this voltage, the flow of current is monitored. In FET current flows from drain through the source, and in this way, the current is controlled by applying a voltage between gate and source. NPN and PNP transistors have the same function of. A current at the base terminal of BJT’s allows a large (current) at the emitter and collector terminal. NPN and PNP transistors are Bipolar junction transistors (BJT) BJT’s control current, which means they only amplify flow. where did the word “transistor” come from? The word is derived directly from the words “transfer” and “resistor” since an electrical current inside the transistor is transmitted across resistors, which are which is a component with two terminals in electronics. Transistors are still utilized in electronic devices in the present. “Transistor is a semiconductor device used to amplify or switch the electronic signals and electrical power.” The Transistor is defining as “The semiconductor device, made of silicon and Germanium.” Transistor Nobel Prize by Nobel Foundation.The year 1977 was when John Bardeen was awarded the Presidential Medal of Freedom. Their original patent title of the transistor is “Semiconductor amplifier Three-electrode circuit component made up of semiconductive material.’ In the year 1956, the team received the Noble Prize in Physics for the invention of the transistor. Shockley, Ph.D., was the director of research in transistors at Bell Labs. Brattain, Ph.D., was an expert on the structure of the crystal structures of the solid at the surface and solid-state Physics. in math and physics at Princeton University, was an expert in the properties of electron conductivity of semiconductors. The scientists responsible for the invention in 1947 that led to the creation of transistors were John Bardeen, Walter Brattain, John Bardeen, and William Shockley. Hence, the question arises here how it controls the electricity it’s discussed step by step. To make the devices applicable to use such a large amount of current or voltage, we have to use DC currents and voltages, so in this case, Transistors play a vital role that can control the CURRENT and VOLTAGE according to our need.
