![]() ![]() The FET or field effect transistors are classified as JFET or junction field effect transistor and MOSFET or metal oxide semiconductor field effect transistor. BJT or the bipolar junction transistors are classified as NPN and PNP transistors. Note: We have two types of transistors – BJT and FET. The details of anode and cathode are given below. A and K are the respective symbols of anode and cathode. Anode and cathode sign are positive and negative. Since transistors are small and produce less heat waste these are preferred for small electrical circuits. What is Anode and Cathode Anode and cathode are electrodes used in an electrolytic cell and electrochemical cell. ![]() It has three terminals namely emitter, base and collector. A transistor consists of two PN diodes connected back to back. Transistors have higher efficiency than vacuum tubes.Ħ). A transistor is an electronic component that is used in circuits to either amplify or switch electrical signals or power, allowing it to be used in a wide array of electronic devices. Transistors consume low power, less heat waste while the vacuum tubes need more power.Ĥ). Transistors cost lower than the vacuum tubes.ģ). Transistors are smaller than the vacuum tubes.Ģ). It can control the flow of electrons inside and is used as a switch and amplifier in electric equipment.īecause of the many advantages of transistors over the vacuum tubes nowadays, transistors are used.Īdvantages of transistors over vacuum tubes are-ġ). One terminal is called the control terminal because the voltage in this terminal controls the resistance between the remaining two terminals.Ī vacuum tube is a sealed glass tube inside of which is in near vacuum condition and allows the controlled passage of electric current. Transistors have very high input resistance and very low output resistance. An anti-parallel diode is called transistor, which means two diodes are. This is because it transfers the resistance from one end of the device to the other end or we can say, transfer of resistance. Transistor is nothing but a transferred resistor (Transistor transferred + resistor). The word transistor is a combination of transfer and resistance. ![]()
