1. If the current is 9.00 A in the primary coil in Problem 13, find the current in the secondary.

2. If the voltage in the secondary coil of a transformer is 110 V and the current in it is 15.0 A, what power does it supply?

3. A neon sign has a transformer that changes electricity from 110 V to 15,000 V

(a) If the primary current is 8.00 A find the current in the secondary coil.

(b) Find the power in the primary coil.

4. A transformer has an output power of 990 W. If the current in the secondary coil is 0.45 A, what is its voltage?

5. The current in the secondary coil of a transformer is 5.00 A. Find the voltage in the secondary if the power is 775 W.
