(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An AC generator produces a voltage of peak value V. The frequency of rotation of the coil of the generator is doubled. The r.m.s. value of the voltage produced is

2. Relevant equations

The answer is V multiplied by [tex]\sqrt{}2[/tex] but I don't understand why.

3. The attempt at a solution

I know that Vrms = Vo/[tex]\sqrt{}2 [/tex]so how does a division become a multiplication?
