A transformer has 490 turns on its primary. An AC source supplies 120 Vrms on the primary and the transformer delivers 9.0 V on its secondary. How many turns are on the secondary? Consider again the transformer described in the problem above. If 25 mA of current is going into the primary, what current is being drawn at the secondary? Please explain/show your work!
An ideal transformer with 5 turns on the primary and 10 turns on the secondary is shown in the figure. A sinusoidal voltage source having V(t) = 10 sin(100t) volts is connected across the primary and a 1 Ω resistor is connected across the secondary. What is the maximum value of the current in the primary circuit (not the secondary)? (answer is 40 amps)

Transformer 10:1 his i 0 12 V Figure 4: Transformer with dc source. Shown in Figure 4 is a very bad way to connect a transformer, which involves a 12 V battery. You may assume that the battery is ideal (i.e., zero internal resistance). The transformer has 10 turns on the primary winding, a saturation flux density of 1.2 T, a core cross-sectional area (Ac) of 10-4 m², and a relative permeability of 100 (i.e., He=100). You may assume that...
