A thin-film nichrome resistor in the form of a rectangle of dimensions 1mm x 5mm is deposited on to a glass substrate. Estimate the thickness of the film for the resistance measured between electrodes contacting the 1mm edges to be 1.0 k2. The resistivity of 'nichrome' may be taken to be 1.07 x100-m. Calculate the surface resistivity of the nichrome film.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
