Wirewound Resistors
Running a small resistor 4W fluorescent lamps?

I can, however, I heard they spent most of the resistance with fluorescent lighting It almost does not use the power of the self-lighting Was a lot. I'm in the UK on 240V line voltage, resistance and 10 watts I use wirewound, but I do not know, I live it How many ohms needed to run a small fluorescent lamp 4w. At Maplin Will come as the rest of fluorescent lamps, the general I'l use ballast, and had become too novice to use Will. E-ICs, there are a range of 10w wirewound resistors are here : Http://www.maplin.co.uk/module.aspx?moduleno=2181

The following analysis only approximate Is through a linear ramp voltage does not vary When it's running now, but the results should be in the ballpark. Answer depends heavily on the average voltage running lamps Whole. For a small lamp, 30V might be. This is your Resistance should be 240-30 = 210V drop means. For lamp 4W, Currently 4W/30V = 0.133A. The resistance of the power dissipation is P = I need * V = 0.133A * 210V = 28W. The rule of thumb, 50 - 60W to say resistance 2 beonhaneun Will. Resistance was R = E / I Resistance = 210V/0.133A = 1580ohm so 28W/4W = 7 times the lamp emission power was wasted. So, the current limit (inductor Or capacitor), than to use the resistance reactance Is recommended. Here are some other elements, plus a capacitor Using Design: Typically, this problem can be started http://www.giangrandi.ch/electronics/neon/neontube.html. The lamp is easy to start you out (earthed) metal lamp Located near the surface. Then the electric field intensity on the surface of the electrode earthed (Almost) Will be stronger than the electrode, it is easier near the electrode Is to create an ionized gas. It's near the metal surface and Once all of the ionization wave in a tube when it is easier. Once the entire length of the tube after the gas long enough to stay Changes in the direction of the current 0.5%, respectively, to maintain a continuous cycle Is ionized, the metal is ionized on the surface is no longer needed. Note: The effect of supply, in this case is generally earthed on one side Depends.
