Describe resistance, including its unit of measurement and symbol(s).

Description should include

• defining resistance as free electrons moving through conductors with some degree of friction or opposition to motion
• identifying the unit of measurement of resistance in ohms and the symbol for resistance (Ω – Greek letter omega) and (R)
• explaining that resistance is measured between two points.

Process/Skill Questions:

• What is the unit of measurement for resistance?
• What letter symbol is used to represent resistance?
• What factors determine how much resistance is in a conductor?
