for a fet an electric field is establishd by the charge present ,that controls the conduction of the output ckt without the need for direct contact between the controlling & control quantities.
MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
FET stands for Field Effect Transistor. The name FET comes because the gate current of a field effect transistor is zero and current present in the source conductor is due to an electric field produced by the substrate material placed between the gate and the source.
Field Effect Transistor A: basically a silicon bar where the conduction is controlled by a field since there is no connection to the gate the impedance is very high
Its a Transistor used in JFET (Junction Field Effect Transistor)
The transistor was created by researchers at the university of Geneva. "The first patent for a field-effect transistor principle was filed in Canada... 1925. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor."

There are two types of field effect transistors:junction field effect transistors andmetal-oxide semiconductor field effect transistors.
A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.
