Resistance
• Free electrons tend to move through conductors with
some degree of friction, or opposition to motion.
• This opposition to motion is called resistance.
• Resistance R is measured in ohms: Ω
• Opposite of the resistance is conductance G:
G=1/R
• Conductance G is measured in Si (siemens) , but
sometimes the unit used is mho (opposite of ohm, used
for R)
