Document Summary

Write down the resistance r. a particular circuit element has a resistance of 1. 25 10 ^ 3 ohms. Use the relationship g = 1 / r to write down g = 1 / (1. 25 10 ^ 3 ohms). Calculate the answer g = 1 / (1. 25 10 ^ 3 ohms) = 0. 8 10 ^ 3 siemens. Write down the current i and voltage v. a voltage of 5 volts generates a current of 0. 30 amps in a wire. Write down ohm"s law: g = i / v. g = 0. 30 amps / 5 volts. Calculate the result: g = 0. 30 amps / 5 volts = 0. 060 siemens. Write down the conductance ohm, the radius r and the length l. find the conductance of a round piece of iron with r = 0. 001 meters and l. Iron has a conductivity of ohm = 1. 03 10 ^ 7 inverse ohm-meters. Calculate the cross-sectional area a = pi r ^ 2.
