Question

You decide to build a small generator by rotating a coiled wire inside a static magnetic field of 0.34 T. You construct the apparatus by coiling wire into 3 loops of radius 0.17 m. If the coils rotate at 2.0 revolutions per second and are connected to a device with 140Ω resistance, calculate the average power ?average supplied to that device Please explain thoroughly and please emphasize on what to do with the revolutions per second. Thank you

Answer 1

The average power Parerase stoppeliked by generater do a device is given as, W 2N²A²B2 Pang= 2R Hers we is the angular frequency, N- mumbes of loops in Cail, = 3 A Area of Cail. = trz [r= 0.17m) B- magnitude of magnetic field. = 0.34T R- Restanu of device = 1400 Criten, angular frugures W=12^ rad 3x 2 rev - At C1 те, из 4л хад, Substitute Value in 2. 1. Plang = (4x)²x 3²x (+X0-173) * (0.34? 2X140 ) Parg = 4.8x10 -3 W
