Difficulty: Easy
Choose an option
Answer
Correct Answer: Volt
Explanation
Introduction / Context:Ohm (resistance), watt (power), and ampere (current) are electrical units. We must select a choice that is also a unit from electricity.
Given Data / Assumptions:
- Stick to SI/derived electrical units.
Concept / Approach:“Volt” is the SI unit of electric potential (voltage). “Hour” is a time unit; “Electricity” and “Light” are general nouns; “Lumen” is a photometric unit (luminous flux), not an electrical unit.
Step-by-Step Solution:
Identify which option is an electrical unit.Select “Volt.”Verification / Alternative check:Physics conventions confirm volt alongside ohm, watt, and ampere as standard units.
Why Other Options Are Wrong:They are not electrical units.
Common Pitfalls:Mixing photometric and electrical units.
Final Answer:Volt
