A 200 Watt power of 30 MHz frequency is used to heat a resin piece of area 150 cm^2 and thickness 2 cm by dielectric heating. This piece of resin has a permittivity of 5 and a power factor of 0.05. So calculate the voltage and current required for this process. If the voltage is to be controlled at 600 V in this process, how much frequency supply has to be used?

We want to investigate how the field strength will be with air as dielectric and with steatite. A plate capacitor is placed in a 24 kV network between phase and ground. The relative permittivity of air is &=1 and for steatite &-6. The plate capacitor has area = 1m². The distance between the electrodes is 2 mm. Ep = 8.854-10-12 F/m A=1m² d=2mm a) Calculate the maximum field strength in the plate capacitor. (Answer: 9.8kV/mm) b) What is the capacitance of the capacitor if we use steatite? (Answer: C = 26.6nF)
