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.
The energy consumed by a 100-watt GLS incandescent bulb produces around 12% heat, 83% IR and only 5% visible light. In contrast, a typical LED might produce15% visible light and 85% heat. Especially with high-power LEDs, it is essential to remove this heat through efficient thermal management. Without good heat sinking, the internal (junction) temperature of the LED rises, and this causes the LED characteristics to change.
