The value of flux involved m the e.m.f. equation of a transformer is____________?
Correct answer: C. maximum value
- A. average value
- B. r.m.s. value
- C. maximum value
- D. instantaneous value
Explanation
The transformer emf equation is written as E = 4.44 f N Φm, where Φm is the maximum value of sinusoidal flux. The average and instantaneous flux values are not the flux quantity used in this equation.
