A piece of Nichrome wire has a radius of 6.5 x 10-4 m. It is used in a laboratory to make a heater that dissipates 3.00×102 W of power when connected to a voltage source of 120 V. Ignoring the effect of temperature on resistance, estimate the necessary length of wire.
Determine the resistance of a conductor 0.60 m long, with uniform diameter of 5.0 cm and having a resistivity which varies as a function of length L measured from one end of the conductor according to the formula: p=0.005+10^(-3) L^2 ohm- m.
The resistance of a metal rod with a conductivity 1.6 x 10^5(ohm-cm)^-1 and a length of 6m is measured to be 0.03 ohms. What voltage is required to produce a current of 5.2 Amperes in this rod?
