Question 1
What is the equation for Ohm's Law?
- V = I/R
- V = I × R
- V = I + R
💡 Hint: It shows how voltage is directly related to current and resistance.
Question 2
True or False: Increasing the voltage in a circuit while keeping resistance constant will decrease the current.
- True
- False
💡 Hint: Consider how voltage affects current.
