The use of induction heating in industrial applications is old and wide. In recent years, this technology was entered to domestic use. This research deals with the analysis and applications of induction heating for cooking food, as these techniques have safe and economy, as well as cleanness and the atmosphere of work comfortable. Knowledge of the electrical resistance of induction heating system is very important to designers working in the high frequency-supplies. This research also analyzes and studies this resistance, by used solid, litz and twisted
wire, and offers simplification of equations derivation help anyone interested in this subject. The MATHCAD V.14 program has been employed to obtain the results. The results presented as general curves for three types of wires (solid, litz and twisted wire) so that a designer can use them without lengthy and complex calculations.
