Consider a transformer where the secondary winding is connected in series to a resistor with resistance R, resulting in an energy dissipation rate of P. Suppose that you wish to increase the resistance to 4R but for P to remain constant. If you are only able to adjust the number of secondary coils, by what factor must you change Ns such that this condition is satisfied? 4. 1 V2 O V2
