What reading level is Electrical Engineering Leaflets Advanced Grade book?
To quickly assess the difficulty of the text, read a short excerpt:
, that is, 1 pound of water raised from 68 to 69 F. , requires an expenditure of 1053 joules, so that, roughly, 1 B. T. U. = 1 kilojoule).
Heat produced in resistance by electrical currents is either purposely developed, as in electric heaters or elec- tric furnaces, or incidentally and unavoidably developed, as in dynamo machinery and wires conveying currents.
202. The flow of heat through a conductor follows the same law as that which determines the flow of electricity through a conductor, i.... E. , Ohm's law. If 6, be the difference of temperature in degrees Centigrade, between two parallel plane surfaces of the conductor, and xS r, the thermal resistance of this portion of the con- ductor, then H, the strength of the thermal current, in joules per second, will be $, is determined as follows ; viz. , if y, be the thermal re- sistivity, Z, the length of the conductor in cms. , and, its cross-sectional area in square centimetres, then #=*-. A The thermal resistivity of a substance is the reciprocal of its thermal conductivity, and may be defined as being equal to the reciprocal of the amount of heat, expressed 195 in joules, which will traverse a cube of the material one cin.
