Voltage. A dimmer usaly chops the sine wave, leting it pass after a while.
Another answerThe dimmer effectively becomes another device in the circuit. It effectively becomes a series circuit, therefore the voltage to the dimmed lights will be reduced in proportion with the relative position of the dimmer switch.HOWEVER...
there is such a thing as "pulse width modulation" dimmers. They are typically used for devices that need full voltage but but you need to reduce output... such as fluorescent lights some fans and many other motors.
Most dimmers are resistance type dimmers since the pulse width modulation dimmers are far more expensive.

How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
What does 1500 watts equal in amps at 120 volts?
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
Does 50 amps rated at 240 volts equal 100 amps rated at 120 volts?
When you multiply amps x volts the product is watts. Using this formula W = Amps x Volts should give you your answer.
200 watts to amps 12v?
To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.
How many amps can handle in 12 volts a 600 volts 15 amps rated terminal bar?
The terminal strip's rating is 15 amps at 600 volts. It does not matter what the voltage is up to 600 volts, the maximum amperage allowed on the strip is 15 amps. It could be 15 amps at 12 volts or 15 amps at 600 volts or any voltage in between.
