A) A simple generator has a 436-loop square coil 24.0 cm on a side.How fast must it turn in a 0.434 T field to produce a 172 V peak output?

B) The output voltage of a 85 W transformer is 13 V , and the input current is 25 A. Is this a step-up or a step-down transformer? By what factor is the voltage multiplied?

Express your answer using two significant figures.

C) A coil has 3.00 Ω resistance and 400 mH inductance. If the current is 3.73 A

and is increasing at a rate of 5.00 A/s , what is the potential difference across the coil at this moment?
