Description should include definitions of voltage, current, and resistance and a summary of their interrelationship, as stated in Ohm's law.

Process/Skill Questions:

• What effect does resistance have on voltage and current in a circuit?
• How are voltage, current, and resistance measured?
• What is the interrelationship of voltage, current, and resistance?
• What happens in a circuit when there is a break or interruption in current flow?
