A portion of Nichrome wire of radiusย 2.90๐๐ย is to be used in winding a heating coil. If the coil must draw a current ofย 8.00A when a voltage ofย 120๐ย is applied across its ends, find the following.ย (Take the resistivity of nichrome to beย 1.50ร10-6๐บ*๐.)ย (a)ย the required resistance of the coilย ๐บย (b)ย the length of wife you must use to wind the coil m If the magnitude of the drifevelocity of free electrons in a copper wire isย 9.48ร10-4๐๐ ,ย what is the electric field in the conductor?ย ๐๐ย Need Help? If the magnitude of the drifevelocity of free electrons in a copper wire isย 9.48ร10-4๐๐
