A voltage of 24 V drives a current of 3 A. What is the resistance?
Answer and explanation
Correct answer: D. 8 ohms
- Step 1: Resistance = voltage / current. Step 2. 24 / 3 = 8 ohms. Answer: 8 ohms. Why not the others: 72 ohms: voltage and current were multiplied. 0.1 ohms: the ratio was inverted. 21 ohms: the current was subtracted from the voltage.
