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 that 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).
Therefore, you should see that the Watt is equal to 1 Joule (J) per second (s).
There is also electrical power which should be considered, and 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
Also, electrical power is 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 outwith the scope of this answer.
The SI unit for power is the watt, symbolized as W.
The SI unit of power is the watt, defined as joules/second. Joule is the unit for energy.
I don't know about SL. If you mean SI, the unit of power is the watt (equal to joules/second).
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".

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.
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).
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, the most commonly derived unit is for electrical power definition, which is the Kilowatt.
The SI unit of power is the watt (W) Other non SI units include horsepower, erg and foot pounds per minute.
