The SI unit of charge, as you know, is a Coulomb (C). The unit of current is the Ampere: 1 A=1C/s. (a) What are the units of resistivity (in terms of the fundamental units of kg, m, s, C)? (b) What are the units of current density (in terms of the fundamental units of kg, m, s, C)? (c) Confirm that equation 24.3 has the same units on both sides of the equal sign. (d) Confirm that equation 24.4a, the microscopic version of Ohm's law, has the same units on both sides of the equal sign. (e) Confirm that equation 24.7, the expression for electrical power, has units of energy divided by time.
