Is the watt depends with the time?

Question

Is the watt depends with the time?

Answer 1

It depends on whether you are talking about Electrical or Mechanical Power !

Formula 1 - Electrical (electric) power equation: Power P = I × V = R × I2 = V2 ⁄ R

where power P is in watts, voltage V is in volts and current I is in amperes (DC).

Formula 2 - Mechanical (mechanic) power equation: Power P = E ⁄ t = W ⁄ t

where power P is in watts, energy E is in joules, and time t is in seconds. 1 W = 1 J/s.

Answer 2

A watt is a unit of power.

1 horsepower is equivalent to 746 watts. In electricity,

1 watt = 1volt x 1 ampere. An time is not a factor.

If you mean household power consumption, that is watt-hour or kilowatt-hour (KWH). And that is dependent with time.

Answer 3

yes

Answer 4

uh, what?
