Question

Q1/ A wind turbine is a device that converts kinetic energy (from wind blowing) into electrical energy.where each side length is 0.35m. It sits in a uniform magnetic field of

0.55T. The turbine turns the current loop inside the magnetic field at a rate of 3600 rotations per minute. (Note:actual wind turbine blades don't spin this fast, so assume there is a gearbox that connects the blades to the current loop.)A generator inside a wind turbine has a 25-turn square shaped current loop i. What is the maximum EMF produced by this wind turbine? ii. Let's say the generator is connected to a resistor R. Would the average power dissipated by the resistor be zero or non-zero? Explain your reasoning.
