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
Principle of Cell: To study electrical principles further we require a source of emf. Although an emf can be produced by any of the six methods discussed above, large amounts o

UV radiations and X - rays are: UV radiations are produced by the high energy transitions of the electrons in atoms. UV radiations have wavelengths ranging from 0.4 m m to 1n
What is the name of the first American physicist to win two Nobel prizes? Ans: (John) bardeen was the first American physicist who win two Nobel prizes.
State Gauss' theorem in electrostatics. Using this theorem, derive the expression for the electric field intensity at any point outside a uniformly charged thin spherical shell.
A bat emits a sound whose frequency is 142 kHz. The speed of sound in air at 20.0°C is 343 m/s. However, the air temperature is 35°C, so the speed of sound is not 343 m/s. Find the
