Nichrome is a nickel-chromium alloy used in heating applications like electric toasters, because it has a relatively high resistivity and heats up when a current passes through it. The resistivity of nichrome is 1.50 × 10−6 Ω·m. Suppose you have a nichrome wire 0.219 mm in diameter and 77 cm long. Required:
a. What is the resistance of the nichrome wire?
b. Find the current when a potential difference of 120 V is connected across the wire's ends.
