We can still talk about resistance of the light bulb according to Ohms law, but we have to do that for a certain voltage. 4) Back to … WebbTypical resistance values range from 10 KiloOhms to 220 KiloOhms. The power dissipation of the required resistor is small, usually less than 1/4 watt, but should be checked for high voltage applications. Typical current for neon lamps is between 0.5 and 3.0 mA. Power dissipation in the resistor can be calculated by the following formula:
