Estimate the given parts of following problem:

Problem: The primary coil of an ideal transformer is connected to a 120-V source and draws 1.0 A. The secondary coil has 900 turns and supplies an output current of 5.0A to run an electrical device.

Part I: What is the voltage across the secondary coil?

Part II: How many turns are in the primary coil?

Part III: If the maximum power allowed by the device (before it is destroyed) is 200W, what is the maximum input current to this transformer?

I need tutor help to solve the above problem and express your answer using two significant figures and also express your answer as an integer.
