A watt is the international standard unit of power, and it is named after the Scottish inventor James Watt. It is defined as the rate of energy transfer per unit time, and it is commonly used to measure the electrical power consumption of devices. One watt is equal to one joule per second, and it can also be expressed as one volt multiplied by one ampere.
What is One Watt Equal To?
A watt is a unit of power. It is named after James Watt, a Scottish inventor who developed the steam engine. One watt is defined as the rate of doing work or transferring energy equivalent to one joule per second.
In other words, one watt is the amount of power required to do one joule of work in one second.
Examples of One Watt
Here are some examples of what one watt can do:
- Power a small light bulb
- Charge a mobile phone
- Run a small fan
- Power a small radio
- Play a CD or DVD
Watts vs. Amps vs. Volts
Watts, amps, and volts are three units of electrical measurement. They are related to each other by the following formula:
Watts = Amps x Volts
This means that you can calculate the power in watts by multiplying the amps by the volts.
For example, a 12-volt battery with a current of 2 amps will produce 24 watts of power.
Table of Power Equivalencies
The following table shows the equivalencies between watts and other units of power:
| Unit | Watts |
|---|---|
| Horsepower | 746 |
| Kilowatt | 1,000 |
| Megawatt | 1,000,000 |
| Gigawatt | 1,000,000,000 |
| Terawatt | 1,000,000,000,000 |
Question 1:
What is the definition of one watt?
Answer:
One watt is the power dissipated by a resistor when one volt is applied across it and one ampere of current flows through it.
Question 2:
How is one watt related to other units of power?
Answer:
One watt is equal to one joule per second. It is also equivalent to 0.00134 horsepower or 0.860 kilocalorie per hour.
Question 3:
What is the significance of one watt in practical applications?
Answer:
One watt is a small unit of power, often used to measure the power consumption of small devices such as light bulbs, fans, and electronic gadgets. It provides a convenient reference point for comparing the power efficiency of different devices.
