Prefix version of 6600 volts

6.6 kilo volts = 6.6 k volts

Explanation:

A prefix is a word, number or a letter that is added before another word. In physics we have different prefixes for the exponential powers of 10, that are placed before units in place of those powers. Some examples are:

deci (d)    10⁻¹

centi (c)    10⁻²

milli (m)     10⁻³

kilo (k)       10³

mega (M)   10⁶

giga (G)     10⁹

We have:

6600 volts

converting to exponential form:

=> 6.6 x 10³ volts

Thus, we know that the prefix of kilo (k) is used for 10³.

Hence,

=> 6.6 kilo volts = 6.6 k volts

energy can cross the boundaries of a closed system in the form of heat and mass
