The heating coil in a toaster is made of nichrome wire with a radius of 0.350 mm. If the coil draws a current of 8.05 A when there is a 120 V potential difference across its ends, find the following.
(Take the resistivity of nichrome to be 1.50 x 10<sup>-6</sup> Ω.m.)
(a) resistance of the coil (in Ω)
Ω
(b) length of wire used to wind the coil (in m)
