Eating or drinking something that's contaminated with germs can cause food poisoning. Often, people get food poisoning from animal-based foods â like meat, poultry, eggs, dairy products, and seafood. But unwashed fruits, vegetables, and other raw foods also can get contaminated and make someone sick.
An LDR or photoresistor is made any semiconductor material with a high resistance. It has a high resistance because there are very few electrons that are free and able to move-the vast majority of the electrons are locked into the crystal lattice and unable to move. photoresistor or light dependent resistor is a component that is sensitive to light. When light falls upon it then the resistance changes. Values of the resistance of the LDR may change over many orders of magnitude the value of the resistance falling as the level of light increases.
Wire Size for LED Lights. Because wire has a certain amount of resistance, there will be a voltage drop as a result. For small gauges, long runs or relative high current loads, this voltage drop can become significant. The amount of light emitted from a LED is a function of the current going through it.
