A diode is an electronic component that conducts current primarily in one direction. It has low resistance in one direction, and high resistance in the other. A diode is made by joining an n-type and p-type semiconductor. n-type semiconductor: doping … more
A thermometer is a device used to measure temperature. There are several types of thermometers, depending on how the temperature is measured. Thermal Expansion: Uses the principle that the volume expands with increasing temperature. Mercury thermometer, alcohol thermometer, bimetal thermometer. … more
All naturally occurring elements CAN exist as a solid, liquid, or gas, and all will have at least one triple point. (except Helium) The triple point is the unique combination of temperature and pressure at which the solid phase, liquid … more
Why we can’t see atoms under an optical microscope? The process by which we see objects is based on light. Therefore, the resolution of object recognition depends on the light. Just as a tool must be precise to open a … more
Diagonals of Polygons Diagonals are lines that connect the vertices of a polygon. However, segments that connect adjacent vertices are not called diagonal. A triangle has no diagonal because all vertices are adjacent to each other. The rectangle can draw … more
Microscope The microscope consists of an objective lens and an eyepiece. The objective lens has a short focal length. The light reflected or transmitted by the object is gathered between the objective lens and the eyepiece. Here a real image … more
