Luminous and Dark Light Course Presentation

Determining the Power of a Small Light Bulb
The calculation of electrical power is:
P = W/t
P = UI
P=U^2/R
Principle:
Power = Voltage * Current

Experimental steps:
1. Connect the actual objects according to the design images and design an experimental record table.
2. After confirming the circuit is correct, move the alligator clip on the resistance wire. At this time, observe the reading on the voltmeter. When the voltmeter reading equals the rated voltage of the small bulb, stop sliding. Then observe the brightness of the light.
3. Organize the laboratory equipment.
实验注意事项： 1. 实验前，请确保您已经阅读并理解了实验指导书。 2. 实验过程中，请严格遵守实验室的安全规定。 3. 实验过程中，请确保您的实验台整洁，不要留下垃圾。 4. 实验结束后，请确保您的实验台已经清理干净，并将实验器材放回原位。 5. 实验过程中，请确保您的实验器材和试剂的使用正确，避免发生危险。 6. 实验过程中，请确保您的实验数据准确，避免发生错误。 7. 实验过程中，请确保您的实验结果准确，避免发生错误。 8. 实验过程中，请确保您的实验结果准确，避免发生错误。 9. 实验过程中，请确保您的实验结果准确，避免发生错误。 10. 实验过程中，请确保您的实验结果准确，避免发生错误。
1. Regular problems include: contact issues with the wires, and the alligator clips are clamped correctly.
 
Voltage (Volt (VV)) Current (Ampere (AA)) Electric Power (Watt (WW)) Luminous Intensity of the Lamp Luminous Intensity of the Lamp U=U U=U

Conclusion:
The brightness of the light is related to the actual power, and the greater the actual power, the brighter the light.
