If we increase the angular frequency to dole (2w), of the alternator described in the problem 3 and 4, the voltage Vrms will be:
10. If the efficiency of the transformer in problem 5 is 98% (which means that 2% of the input power is lost as heat), what will be the secondary current?

10. Si la eficiencia del transformador del problema 5 es de 98% (lo que quiere decir que 2% de la potencia de entrada se pierde en calor), ¿cuál será la corriente secundaria? a)1.5 Amp b) 3.3 Amp c) 11.8Amp d) 21.8Amp e) 30.4 Amp
e) 21.21V 5. Si aumentamos la frecuencia angular al doble (2w), del alternador que se describe en el problema 3 y 4, el voltaje V sera: RMS a) La mitad b) Igual c) El doble d) Se reducira por la raiz de 2 e) El voltaje de salida de ese generador no depende de w.
3. Considere una espira de alambre que se hace girar a una velocidad angular w entre los polos de un imán tal que el flujo magnético a través de esta es: D (t) = BA cos(wt). Encuentre una expresión para la fuerza electromotriz inducida, Emf= - dd (t)/dt. arriba abajo ve escobillas
