Is a light bulb an inductive load or resistive load?
A light bulb is a resistive load.
Why most of the practical loads are inductive?
Most loads are actually resistive, such as an incandescent (normal) light bulb or electric heat or cooking equipment. Other loads are mostly inductive because they incorporate either transformers or motors, which are both inductive. Off hand I cannot think of a normally capacitive circuit, which would be the opposite of inductive.
When was the fluorescent light invented?
The fluorescent light was invented in 1903 by Peter Cooper Hewitt. Peter Cooper Hewitt was an inventor and an electrical engineer.
What is the difference between fluorescent and incandescent?
In an incasescent light the light is emitted directly from the element. In a fluorescent light the element excites a gas which in turn excites a secondary emission surface this then emits the light. Less power is needed per candella of light emitted from a fluorescent light but it is more expensive to make in the first place. This is correct, as mentioned above, I found this article written by Specialist Paints Online with gives a comparison http://www.specialistpaintsonline.co.uk/news/Luminous-and-Fluorescent-Paints
What is meant by leading and lagging pf?
Power Factor is the ratio of true vs apparent power, and comes into play with a reactive (inductive or capacitive) load. A purely resistive load, such as a light bulb or toaster, will have a power factor of 1 because the current is in phase with the voltage. An inductive load, however, such as a motor, will have a power factor less than 1 because the current lags the voltage. You could also have a capacitive load, with a power factor less than 1, but in this case the current leads the voltage.AnswerThe terms, 'leading' and 'lagging' refer to whether a circuit's load current is leading or lagging the supply voltage. Current will 'lead' in resistive-capacitive (R-C) circuits, and 'lag' in resistive-inductive (R-L) circuits. So, a 'leading power factor' indicates a leading current, and applies to R-C circuits, while a 'lagging power factor' indicates a lagging current, and applies to R-L circuits.
Is a light bulb an inductive load or resistive load?
A light bulb is a resistive load.
How does a fluorescent light fitting operate?
mercury
What types of light bulbs are used in electric circuits?
Usually the light bulbs used are resistive components, but the energy savers used now a days are inductive components and they are used because they consume reactive(inductive) less useful power and save useful or real (resistive) power.
Does a fluorescent light fitting with 4 x T8 2' 18W tubes and a 48W ballast use all 120W when running?
No, a fluorescent light fitting with a 4xT8 2' 18W tube and a 48W ballast does not use all the 120W when running.
Can choke be replaced by a resistor in a fluorescent lamp?
Yes it can. However, certain tubes will not fire on just the mains voltage and these are no good with a resistive ballast. T5 types in particular need the high voltage spike from an inductive ballast. Generally, T12 20W and 40W tubes, and T8 10W and 15W tubes will start with a resistive ballast. It is usually necessary to earth the fitting to help starting. A conventional glow tube starter is used in the normal way. A resistive ballast has to be used when the mains supply is DC. Special resistance lamps have been made for the purpose, but ordinary incandescent lamps can be also be used, as well as a conventional wirewound resistor. Commercially made fluorescent lamps with resistor ballasts have been made. Eg. the Mazda Netaline, and also various fluorescent adaptors that plug into an incandescent light socket where the weight of a iron core ballast is problematic.

The lagalities regarding modifying a fluorescent light batten holder for fitting a led light t8 tubeI will be bridging the ballast and removing the starterI am a competent person1?
No. You are not.
What are inductive load?
Any devices that have coils of wire in there manufacture can be classed as inductive loads. e.g. motors, solenoids and contactor coils are a few. Example of resistive loads can be baseboard heaters, filament light bulbs, toasters and stove top elements.
How do you remove a non-integrated bi-pin double-turn compact fluorescent lamp?
Pull the light globe straight out of the fitting. No twisting.
Why does the fluorescent light use more energy than other lights?
A fluorescent light actually uses less energy.A fluorescent light actually uses less energy.A fluorescent light actually uses less energy.A fluorescent light actually uses less energy.A fluorescent light actually uses less energy.A fluorescent light actually uses less energy.
Can one replace a tungsten bulb with a compact fluorescent bulb?
Yes, if it fits the socket and the light fitting, or lamp fixture, with its cover or shade. You will not be able to dim the compact fluorescent as you did the incandescent (unless you have a really fancy dimmer).
How is fluorescent different from natural light?
Well.. the difference is that fluorescent light isn't natural and natural light isn't fluorescent . its not rocket science (:
