Question 1: What is the formula for Ohm's Law?

Answer: V = I * R

Question 2: Multiple choice: Which of the following units is used for resistance?

Answer: Ohm

Question 3: True or False: Increasing the resistance in a circuit will increase the current, assuming voltage is constant.

Answer: False

Question 4: Explain the relationship between voltage, current, and resistance in Ohm's Law.

Answer: Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
