Q

The unit of electrical power is:

🔍 Key Concepts

• Electrical power vs. energy – understand the difference between power (rate) and energy (quantity) • The SI (International System) unit for electrical power • How units per second often indicate a rate (which relates to power)

💭 Think About

• Is electrical power describing an amount of energy stored, or how fast energy is used or produced? • What is the name of the SI base unit commonly used for light bulbs and engines when we describe power output? • How is a joule defined, and what happens to its meaning if you divide it by seconds?

✅ Before You Answer

• Confirm the SI unit name used on appliances (light bulbs, heaters) to show power rating • Check whether joule is originally a unit of energy, not power • Verify whether joule per second matches the definition of power as energy per unit time
