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>
40. External Peripherals of a Computer systems are the following:
-> Keyboard – this is an input device
-> Mouse – This is an input device also
-> Printer – this is an output device
-> Flashdrive – This is a storage device
-> Monitor – this is an output device
-> external hard drive – this is a storage device
Output device are those devices that communicate the results of the data processing to the user
Input device are those device that communicate the results of the data processing to the computer system
Storage device are those device that stores data.
