(A).3.3KW(B).0.33KW(C).3.3KW(D).3.3kw
The options you provided are:
(A) 3.3KW
(B) 0.33KW
(C) 3.3KW
(D) 3.3kw
To determine which option is correct and represents the correct unit, we need to understand what "KW" stands for. "KW" is an abbreviation for kilowatts, which is a unit of power. Power is the rate at which work is done or energy is transferred.
In this case, all the options provided have the same numerical value, which is 3.3. The only difference is the letter case of the unit.
To identify the correct option, we need to pay attention to the standard representation of units. In the International System of Units (SI), unit symbols are written in lowercase letters, unless they are derived from proper names. Therefore, the correct representation for kilowatts is "kW" with a lowercase "k" and uppercase "W."
Based on this, option (D) "3.3kw" is incorrect because it does not follow the standard unit representation. The correct option is (C) "3.3KW" as it correctly represents kilowatts with a lowercase "k" and uppercase "W".
