What does P stand for in physics electricity?

Electric power (P) is simply the product of current times voltage. Power has familiar units of watts. Since the SI unit for potential energy (PE) is the joule, power has units of joules per second, or watts. Thus, 1 A ⋅V= 1 W.

#### What is μ in math?

μ = ( Σ Xi ) / N. The symbol ‘μ’ represents the population mean. The symbol ‘Σ Xi’ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on. The symbol ‘N’ represents the total number of individuals or cases in the population.

What is Ø in physics?

Ø is used for the empty set and I think they should have use ∆Q not ØQ. ∆ is used to denote a finite amount of something:∆t-some amount of time, ∆x some distance in the x direction,∆Q some charge.

What is Ø in math?

The letter “Ø” is sometimes used in mathematics as a replacement for the symbol “∅” (Unicode character U+2205), referring to the empty set as established by Bourbaki, and sometimes in linguistics as a replacement for same symbol used to represent a zero. Slashed zero is an alternate glyph for the zero character.
