A little.
First off, most modern dimmer switches aren't rheostats. Those have been supplanted by TRIACs (triode for AC), and later, IGBTs (insulated gate bipolar transistors). For both of these, their mode of action is to change the duty cycle of the AC wave (duty cycle is time on versus cycle time) such that less power per cycle is put through the bulb. This is more efficient than a rheostat, in that, there isnt as much resistive loss across the dimmer.
The resistive loss is where the "a little" comes in. For all three types, a small amount of the power put through the dimmer is dissipated as heat - however, this is significantly less than the reduction in output power to the bulb, whatever the type.
An ideal dimmer would have 100% efficiency - that is, for a given setting, it would dissipate no heat, and the bulb would be the only thing on the circuit consuming power. However, no component is ideal, and modern dimmers typically consume under 1% of their power throughput (so if it's passing a total of 1W, it'll consume less than 10 milliWatts).
A buzzing noise from a standard incandescent lighting fixture can be caused by a short in the lighting circuit (which is dangerous), or in some cases it can happen using a rheostat that is not all the way on or all the way off. The larger the physical size (not necessarily wattage) of the filament, the more likely it is to buzz using a dimmer -- these bulbs are designed for 120 volts, and using a rheostat gives less voltage to the lamp.A tube fluorescent fixture can make a buzzing noise if the ballast (small electrical box inside the fixture) is beginning to fail.Some outdoor fixtures are inherently noisy, such as a sodium arc lamp. In this case, there is really nothing to be done about it.
Check the ballast for the amperage and multiply it by the working voltage. This will give you the wattage that the fixture draws.
A lock is a fixture, same as a light, sink, tub. A fitting is usually a part of a fixture, or a fixture is made up of fittings.
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
A fixture is what the light bulb goes into.
The fixture construction has nothing to do with the amount of energy that the fixture uses. It is the lamp in the fixture that draws the amperage. This amperage times the fixtures voltage is what gives you the fixtures wattage. W = A x V. Watts = Amps x Volts.

Yes
Turning off an electrical fixture is a good way to save money, but unplugging it is better. Since you turned off the appliance, and not able to unplug the cord, still it will consume some electricity. So when you unplug it, you save more money!
The moisture prevents buildup of static electricity that attracts the dust to the furniture.
There would be power there because the "neutral" is the path electricity mostly used to return to its source. All electricity has to return to its source somehow.
No power is used. The lamp in the light fixture is the load of the circuit. The load resistance is what makes the current flow. When the current flows through the filament's resistance, heat and light are generated. With no lamp in the fixture, the circuit's voltage potential is still at the socket contact points and if touched could cause you a shock. This is a good reason to shut the fixture off at the switch when removing the burnt out bulb and replacing it with a new one.

what is a sentence for fixture
"Fixture" generally refers to things permanently attached to the structure. A light fixture would be one example, screwed to the wall or ceiling. The light fixture, also called a luminaire, would include devices for holding the lighting elements, supplying electricity to them, enclosing the connections for safety, and means for attaching it to the electrical supply permanently. A "fixture" could, in theory, dangle from a cord permanently attached to a suitable support. For contrast, a cord-connected device would not be a fixture. In fact, it is often illegal to use cord and plug on any appliance that is permanently attached (e.g., screwed in or with water pipes attached).
It would be a fixture.
