Was it installed in a three way or four way system?
Probably not, since a volume control switch is designed for extremely low current measured in fractions of a watt, while a dimmer switch is typically capable of handling several hundred watts.
This simple if you have two switches controlling a set of light you will need to buy a three way switch. A three way switch will have a place for three connection. Depending on what brand of switch you purchase the directions will be sightly different but most dimmer come with detailed directions and diagrams. When you by a dimmer you need to read what kind of load it is meant to control. They are built to control incandescent light, magnet low voltage lights or electronic lights.
If you're really lucky, you'll just have no power going to the light. You could very easily short out across the circuit breaker. Dimmers are not intended to be used in series, which would be the only way to hook them up in place of 3-way switches. This does not apply if you can find 3-way dimmer switches. They are expensive and fairly uncommon, but there are a few out there. It's always best to have any electrical work performed by a licensed, bonded electrician.
As many as the watts or current the dimmer specs say it will control - less 10 percent
You can wire a dimmer into any circuit. The issue is where you do it for a specific outlet. The dimmer would just have to connect to a single outlet and not all outlets on the same circuit. The issue is getting a dimmer that is compatible with the device you are dimming. Some lighting requires special dimmers.
A person could buy discounted dimmer switches from Discount Dimmers. Another option is from Amazon. These discounted dimmer switches prices at $10 and up.
Answer Actually dimmer switches extend the life of a light bulb, especially if you dim them often.
Dimmer switches go bad, more often than regular switches.

Yes.
A dimmer switch is very helpful as if you attach one to your light switch you can control your light intensity, the Lutron Dimmer is a brand dimmer switches that provide high quality performance.
I think you may be talking about the dashboard dimmer switches.
Down by where the dimmer switches were once located.
Older types of dimmer switches used a small transformer in them for a control power supply. Change this unit out for a new one as the technology has come a long way in the past few years.
Nothing . . . obviously.
All dimmer switches hum. The older they get, the louder the hum. If you have compact florescent bulbs in the fixture, this will cause the switch to hum louder.
