A hair dryer uses 12.5 A of current when it is plugged into a 120 V current. What power is produced by the hair dryer?

P=IV

=12.5*120

=1500W

=1.5KW

I think the equation for Power is Current x Voltage

The power is 1500W (watt)

P=vxi watts

Electrical power is measured in watts. In an electrical system power (P) is equal to the voltage multiplied by the current.

P = VI = 120V * 12.5A = 1500W

12.5 x 120 = 1500 watts

The apparent power is measured as Voltage * Amperage: 12.5 * 120 = 1500. However, in order to get the true power (Watts) you would need to multiply by the cosine of the phase shift, for a 50 degree phase shift this would 64.2% for instance.

Simple answer, just look for the "Watt" rating on your hairdryer. It will be a lot easier that way :-)

Okay, correction. 120 V is not current, it's AC Peak to Peak Potential (or Voltage); that's okay though I know what you meant.

First off, with AC power uses RMS wattage which in a nutshell is the potential times the square root of one half (0.7071 which is also the sine of 45 degrees) times the current flow. Thus 12.5 amperes of draw in AC is equivelent to roughly 1060 watts or 1.4 horse power.

The only thing produced by the hair dryer is heat. This device consumes power, not produce it.

mmm... the current must not be in Volts... but the power is 1500VA (or watts with DC) and if you're using AC, the power is 1500 VA = 1061 Watts.

P = V*I (watt)

do is baby!

This is as easy as Pie because the formula looks like PIE

P = I * E

Where P is the power measured in watts, I is the current measured in amperes, and E is the electromotive force measured in volts. Plug in the values:

P = 12.5 * 120 = 1500 Watts

About RMS and power factor: 120 volts AC is the RMS, not peak-to-peak or even zero-to-peak, voltage. It is common practice to specify AC current as an RMS value as well (see ref.) The wattage in a resistive load, like the heater part of a hair dryer, does not have any phase angle. This load dominates the total dryer power. The relatively low-power blower motor does have a phase angle, so there is probably a small angle in the overall dryer power. The power drawn will be very close to 1500W.
