what is the full form of commerce and the unit of power
Answers
Answer:
unit of power is joule.....
Step-by-step explanation:
Power, in general, is defined as the rate at which energy is transferred or converted or the rate of doing work. Thus, power can be calculated using the formula P = W / t. On the other hand, power is a scalar quantity and is basically the amount of energy consumed per unit time which has no direction. While we have already talked about power in our other article, on this page students will find all the information regarding the unit of power.
SI Unit of Power
According to the popular standards, the SI unit of power is none other than watt which is represented by the symbol W). One joule per second is also equal to one watt. Interestingly, the name was kept in recognition of James Watt, who invented the condenser for the steam engine. He also coined the term horsepower, which is the older unit of power. It can be depicted as;
1 watt = 1 J/s = 1 kg-m2/s3
Other Power Units
Some of the common power units include ergs per second (erg/s), foot-pounds per minute, dBm, food calories per hour or kilocalories per hour, horsepower (hp), BTU per hour (BTU/h).
