Heating coil is to be made, from nichrome wire, which will operate on a 12 V supply and will have a power of 36 W when immersed in water at 373 K. The wire available has a cross-sectional area of 0.10 mm². What length of wire will be required? (Resistivity of nichrome at 273 K = 1.08 x 10-6 Ωm. Temperature co-efficient of resistivity of nichrome = 8.0 x 10-5 K-1.) (Ans is 0.3733 m ) #OnlyForPhysicsTopper
