Chapter 27 Current and Resistance The Development of Voltage
... The SI unit of resistance is the ohm (Ω). 1 Ω=1 V/A The electric field within a wire accelerates the electrons. However their velocities do not increase indefinitely because they collide with the array of positive ions that form the crystal lattice. This steady drift is analogous to the terminal vel ...
