Description

• A portion of Nichrome wire of radius 2.90𝑚𝑚 is to be used in winding a heating coil. If the coil must draw a current of 8.00A when a voltage of 120𝑉 is applied across its ends, find the following. (Take the resistivity of nichrome to be 1.50×10-6𝛺*𝑚.) (a) the required resistance of the coil 𝛺 (b) 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 is 9.48×10-4𝑚𝑠, what is the electric field in the conductor? 𝑉𝑚 Need Help? If the magnitude of the drifevelocity of free electrons in a copper wire is 9.48×10-4𝑚𝑠
