What is Ohm's Law?
💡 Hint: Think about how these three readings interact.
If you have a voltage of 12V and a resistance of 3Ω, how much current flows?
💡 Hint: Use the formula V = I × R.

Challenge Problems
Push your limits with advanced challenges
In a circuit, if the voltage is 30V and the current is 5A, what is the resistance? Can you apply any known formula to find out?
💡 Hint: Look for the relationship in Ohm's Law.
A device operates at 240V and consumes 10A. If you want to switch to an alternative device, but keep the same power, what resistance should that device have?
💡 Hint: You will need to rearrange the power formula using Ohm's Law.
