Question
What is the voltage across a 2-ohm resistor if a current of 0.5 amperes flows through it?
Answer Options
- A) 1 volt
- B) 0.25 volts
- C) 2.5 volts
- D) 1.5 volts
Correct Answer: A
Explanation
Using the Ohm’s Law formula for voltage: E = I \times R (T5D02).
E = 0.5\text{ A} \times 2\text{ Ohms} = 1\text{ Volt}. This calculation allows you to find the voltage drop across a specific component in a circuit.
