Explain Ohm’s law.

Explanation should include that

• Ohm’s law is the fundamental equation that relates voltage, current, and resistance in a purely resistive circuit according to V (voltage) = I (current) x R (resistance).
• electrical current in a circuit or conductor will always be proportional to the voltage across the conductor or circuit and inversely proportional to the total resistance.

Process/Skill Questions:

• What is an equation for Ohm’s Law?
• How can current be calculated if resistance and voltage are known?
