The power required for dielectric heating of a slab of resin 150 cm2 in area and 2 cm thick is 200 W, at a frequency of 30 MHz. The material has a relative permittivity of 5 and power factor of 0.05. Find the voltage necessary and the current flowing through the material. If the voltage is limited to 700 V, what will be the frequency to obtain the same heating? The value of the resistive component of current (i.e. IR) is negligible. operation
