1. The problem statement, all variables and given/known data The maximum indicued emf in a generator is 205rpm is 43.0V. How fast must the rotor of the generator rotate if it's to generate a maximum inducded emf of 55.0V? 2. Relevant equations E= NBAsinwt 3. The attempt at a solution 205r/m*2 (Pi)/ 1rev81min/60s = 21.46rad/s magnet field isnt given, so how can u solve this?
