When does a thermocouple produce electricity?
A thermocouple produces electricity when there is a temperature difference between its two junctions. This temperature difference creates a voltage potential that generates electrical current.
What is the relationship between static electricity and voltage?
Static electricity is a buildup of electric charge on an object, while voltage is the measure of electric potential difference between two points. The relationship between static electricity and voltage is that static electricity can create a voltage difference when there is a buildup of charge, leading to the potential for electrical discharge or sparks.
What is the difference between light and energy?
Light is a form of electromagnetic radiation that is visible to the human eye, while energy is the ability to do work. Light is a specific type of energy that can be harnessed to perform tasks like illuminating a room or generating electricity.
Difference between static electricity and dynamic electricity?
Static electricity is the buildup of an electric charge on the surface of a material, causing it to attract or repel other objects. Dynamic electricity, on the other hand, is the flow of electric charge through a conductor, such as in a circuit. Dynamic electricity is what powers most electrical devices and systems.
What is the difference in brightness between a 60W and 100W light bulb?
The 100W light bulb is brighter than the 60W light bulb. The difference in brightness is 40 watts.
