Can the GU10 type light bulb be used with a dimmer

GU10 is not a bulb type, it is a base type (Twistline). Typically, you would see this on a halogen bulb, which can be dimmed if you get a dimmer with the appropriate voltage and current rating.

Here is an example of a bulb:

thank you guys. One more question if the light I need to dim is on a 3 way switch which end can I connect a dimmer to?

Either end will dim the bulb, put it where it will be most convenient to use it.

They do make three-way dimmers.

And, given the right budget and equipment, almost any lamp can be dimmed. This includes arc lamps and flourescent lamps. Flourescent lamp dimmers can now get down to 10%. It's pretty cool to see a 4' tube just barely glowing...

In a 3-way, be sure to get a dimmer designed as a 3 way. Otherwise, one the other switch wil just give you on/off/.
