Yes. The Rheostat creates more resistance, and therefore less luminaries are produced.

Well thanks for the feedback so far all. I have low voltage fittings which use MR16 bulbs and I purchased transformers which are dimmable. However I may have got some of the light switch's wrong. I thought all you do is add up the total Watt for the number of lights you have and then get a dimmer switch which has a Watt rating above that. e.g. For 4 x 50 Watt I have used 250 Watt dimmer modules. And for 6 x 50 Watt I have use a 400 Watt dimmer module. They do hum I have noticed however someone said to me that when you dim the lights the difference in power is simply used up by the dimmer module hence why it gets hot! I will look at Toolstation ( who I have used loads during this project) but I didn't realise that this was so complecated at all. I thought dimming the lights would save electricity plain and simple. But things never appear to be as simple as you may expect :) Thanks so far all!

Yes. The dimmer reduces the current that goes to the light. Less electricity = less light.

No. The light bulb itself will use less electricity (which could lead to longer bulb life), but overall, you will use the same amount or possibly slightly more of electricity. The power which is not dissipated in the light bulb will be dissipated in the dimmer.

It depends. Some older switches use resistors to just burn off the excess electricity into heat and some newer ones just don't allow the current in in the first place. But they also cost more.

Yes, as less is sent to it. The dimmer, called a rheostat (spelling?) simply cuts down on the amount of current.

It reduces the total power going to the bulb by 'chopping out' part of the AC waveform.

Absolutely, when you dim the light, you've lowered the voltage. Lowering the voltage means less use of electricity.
Good Luck, ;-)

Yes, it should, otherwise ur dimmer would turn into a heater. Just touch it and find.

Yes. It's a three way bulb system, the lower you set it, the less wattage used to light the succession of bulbs.
