A current of 3 A flows through a resistor of 6 ohms. What is the potential difference across the resistor?
Answer and explanation
Correct answer: D. 18 V
- Step 1: .
- Step 2: V.
Answer
18 V.
Why not the others: 2 V: resistance is divided by current. 0.5 V: current is divided by resistance. 9 V: the numbers are added.
