Calculate the resistance of a 5.46m length of lead strip, 0.450cm wide and 1.25mm thick. What length of similar strip, but made of copper, would have to be put in parallel with the lead strip for the effective resistance of the combination to be 0.100 ohm? (Resistivity of lead = 20.6 × 10E-8 Ohms meter; of copper = 1.72 × 10E-8 Ohms meter)
