Q. Why nichrome is used as heating element in electric heating devices?
Nichrome, an alloy of nickel as well as chromium is used as the heating element for the following reasons.
(1) It has high precise resistance
(2) It has elevated melting point
(3) It is not easily oxidized
Weber; Wb (after W. Weber, 1804-1891): The derived SI unit of magnetic flux equivalent to the flux that, relating a circuit of one turn, generates in it an electromotive force
