10. Consider a simple transformer that has 100-turn primary coil and a 1000-turn secondary coil. The primary is connected to a 120-V AC source and the secondary is connected to an electrical device with a resistance of 1000 ohms.
a. What will be the voltage output of the secondary? ...........................
b. What current flows in the secondary? ........................
c. Now that you know the voltage and the current, what is the power in the secondary coil? ......................
d. Neglecting small heating losses, and knowing that energy is conserved, what is the power in the primary coil
