Describe the interrelationship among current, voltage, and resistance.
Description should include
- explaining how current in a circuit depends on the amount of voltage available to move electrons while resistance opposes electron flow
- explaining why the amount of electrical current through a metal conductor in a circuit is directly proportional to the voltage impressed across it.
Process/Skill Questions:
- How are current, voltage, and resistance related?
- How does resistance affect the movement of free electrons?
- What are the standard units of measurement for current, voltage, and resistance?
