Start. A transformer is connected to a wall socket as shown above. The graph shows the primary voltage Vp (black) and the secundary voltage Vs (red). How many turns Ns does the secundary coil carry when the primary coil carries Np = 200 turns?

(Answer).

Start. A transformer is connected to a wall socket as shown above. The graph shows the primary voltage Vp (black) and the primary current Ip (red). Determine the electrical power send into the transformer.    (Answer).

Also determine the effective current going through the resistor on the secundary side.  (Answer).

(Assume no heat loss in the transformer).
