The test. -Connect the positive of the power cord on the leg, with 10 business code pakhao lalot of TL 494.-Cut the cable connection between the legs of the IRF740 MOSFET with Dain of the Fly back transformer.-Plug the power supply into the circuit and adjust VR1 until the Duty cycle values displayed on the screen on an equal business code p 10% lalot.-The positive and negative battery cable to the Spark gab, and then adjust the distance between the terminal block of the Spark gab channel until there is a break down in the air, and then use the Copper River, measuring the distance between the Seagull (d) pole with record results.-Try repeating the message to 2.4 2.2 but the Duty cycle is equal to 20%, 30%, 40% and 50%, respectively.-Bring up the distance between the average Duty cycle for each pole to calculate values for voltage (V), electric charge which can be induced (q). and performance ("ff", "_" E), by replacing in the equations.-When E is the electric field in the air, that is, to break down 30 kV/cm. V is the voltage of electricity generated by electric charge (V) D is the distance of the Spark gap in each box (cm) Davg Spark gap is the distance of the average (cm) Q is the electric charge induced created (C) "E" _ "invention" is ff's performance on average (per cent)
