Question
What is the resistance of a circuit in which a current of 3 amperes flows when connected to 90 volts?
Answer Options
- A) 3 ohms
- B) 30 ohms
- C) 93 ohms
- D) 270 ohms
Correct Answer: B
Explanation
Using the Ohm’s Law formula for resistance: R = E / I (T5D03).
R = 90\text{ V} / 3\text{ A} = 30\text{ Ohms}. This shows that a load that is connected to a 90\text{ V} source and draws 3\text{ A} must have a total opposition to current flow of 30\text{ Ohms}.
