Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>
The correct answer isn’t really a choice shown. I would choose D because if a work doesn’t have a copyright symbol that doesn’t mean it’s in the public domain. In a real life situation it would be best to ask the creator before you use their work. If they say it’s in the public domain then you’re fine, but even if they say you can use it that doesn’t mean it’s in the public domain, it just means that you have permission to use it.
