Top Answer

The SI units for mechanical and electrical Power are the Watt (W), and the Watt (electrical) (We) respectively.

Power is the rate of doing work, or at which energy is converted. It can be thought of as - "amount of energy used to perform work, or converted from one form to another, in a specified period of time, namely, in a second".

The equation is P=W/t, where P is Power, W is the work done and t is the time taken. The equation, P=E/t, where E is the amount energy used to do the work, means the same thing. The unit for Energy is the Joule (J), and the unit for time is the second (s). The unit of power is then the watt,which is equal to 1 Joule (J) per second (s).

Electrical Power

There are a few different formulae depending on whether voltage, current or resistance are being considered. Electrical power is equal to the amount of current times the voltage, or P=IV. Electrical power is also equal to the current squared times the resistance, P=I2R

There are other formulae for the average electrical power of a sinusoidal voltage, but this is beyond the scope of this question.

There is no SI Base Unit for power. The unit for power is the watt, which is a Derived Unit.

the answer for the si unit of power is the watt or w

That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power".

The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.

The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.

The SI unit of power is the watt, defined as joules/second. Joule is the unit for energy.

The unit of power in the SI is watt; 1 W = 1 J/s.

... is called power. The SI unit for energy is the joule; the SI unit for power is joule/second = watt.

Watt = SI unit of power Volt = SI unit of electric force

The derived SI unit for power is 1 newton-meter of energy per second.That unit is given its own name: the watt.

There is no SI base unit for power.Power is measured in watts, which is a derived unit, not a base unit.A watt is equal to one joule (newton-meter) per second (J/s).

Please don't write "these", implying a list, which you don't provide.The SI unit of power is the watt = joules/second. The SI unit of energy is the joule.

Horsepower is a unit of power. 1 horsepower = 745.699872 watts The formula for Power is this: Power = Work/TimeThe SI unit of power is the watt (W), which is equal to one joule per second. The SI unit for work is the joule (J). The SI unit for time is seconds (s).

it is watt

Watt.

The official SI unit of power is the watt, which is equal to one joule of energy per second (J/s).

The SI unit of power is the watt (W), which is equal to one joule per second.

The Watt is the SI unit of power. Current xVoltage =Watts

The SI unit for power is the Watt, the most commonly derived unit is for electrical power definition, which is the Kilowatt.

The SI unit for power, thermal or mechanical, is the watt, W. 1 W = 1 J/s (joule/second).

Power is measured in watts (W) in the SI system.

Diopter (D)...

The SI unit of power is the watt (W) Other non SI units include horsepower, erg and foot pounds per minute.
