An electric generator is constructed using a permanent magnet with magnetic field magnitude, 10mt. a circular loop of wire of radius, 50cm is rotated at a rate of 5 rev/s. (a) write an expression for the power output (as a function of time) by a lightbulb with resistance 15kω which is hooked up to this generator.
(b) would the power output increase or decrease if we decrease the resistance of the lightbulb?
