resistor is made of a material with resistivity ρ = 3.5×10^−3Ωm. It is 1.2cm long and 0.5cm indiameter. (a) What is the resistance of this resistor? (b) If 10Vare applied across it, what is thecurrent through this resistor? (c) In the case of part (b) how muchpower is dissipated by the resistor?(d) If the electric company is charging $0.25 per kilowatt-hour,how long must we apply this voltagebefore we are charged 1.00 (ignore temperature effects)?
