RELATIVE AGE. The Law of Superposition states that in a layered, depositional sequence (such as a series of sedimentary beds or lava flows), the material on which any layer is deposited is older than the layer itself. Thus, the layers are successively younger, going from bottom to top.
A current-controlled, three-terminal semiconductor device used for the control and amplification of electronic circuitry is called transistor
A transistor is a semiconductor device that switches or amplifies electrical impulses. The transistor is one of the fundamental components of contemporary electronics. [1] It has at least three terminals for connecting to an electronic circuit and is made of semiconductor material. The current flowing through another pair of the transistor's terminals is controlled by the voltage or current provided to one set of those terminals. Because the regulated (output) power might be higher than the controlling (input) power, a transistor can amplify a signal. Although many more transistors are found embedded in integrated circuits, some are packaged individually.
