What are the characteristics of Zener diode? Zener Diode Specifications Zener/Breakdown Voltage – The Zener or the reverse breakdown voltage ranges from 2.4 V to 200 V, sometimes it can go up to 1 kV while the maximum for the surface-mounted device is 47 V. Current Iz (max) – It is the maximum current at […]
What are the types of DFD?
What are the types of DFD? DFD is of two types: Logical DFD: Logical data flow diagram mainly focuses on the system process. It illustrates how data flows in the system. Physical DFD: Physical data flow diagram shows how the data flow is actually implemented in the system. Physical DFD is more specific and close […]
Why can a magnet attract an Unmagnetized nail?
Why can a magnet attract an Unmagnetized nail? Stroking material containing iron with a magnet, placing a piece of iron in the strong magnetic field, placing a piece of iron near a strong electromagnet. The reason a magnet can attract an unmagnetized nails is that? nails become temporarily magnetized in a magnetic field. Why can’t […]
Who found atom first?
Who found atom first? Democritus Why can’t scientists see inside an atom? Almost all of an atom’s mass comes from the protons and neutrons in the nucleus. However, because electrons orbit around the nucleus, most of an atom is empty space! You can’t see atoms with the naked eye, because they’re simply too small. Using […]
Is it possible for a solid metal ball to float in mercury?
Can a mixture of sawdust and water be separated by filtration?
Can a mixture of sawdust and water be separated by filtration? Answer. Answer: No, sawdust and water cannot be separated by sedimentation or decantation. But instead can be separated by evaporation. How will you separate a mixture of saw dust and sugar? Iron filings can be separated by magnetic separation method. When water is added […]
Is spring water the same as distilled water?
Is spring water the same as distilled water? Spring water is just as its name implies—water from a natural spring. By leaving the minerals and trace electrolytes in the spring water, you’ll get a crisp, fresh water taste. If you’re asking, “Is spring water distilled?” The answer is no, spring water is not the same […]
What are two examples of a precipitate?
What are two examples of a precipitate? Some examples of precipitation are rain, hail, sleet, and snow. Condensation is when cool air turns water vapor back into liquid and makes clouds. How do you tell if a product is a precipitate? An ionic solution is when the ions of a compound have dissociated in an […]
How is an experiment accurate?
How is an experiment accurate? A measurement is reliable if you repeat it and get the same or a similar answer over and over again, and an experiment is reliable if it gives the same result when you repeat the entire experiment. How many times should you test an experiment? For a typical experiment, you […]
Why do electrons move freely in metals?
Why do electrons move freely in metals? The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. When nonmetals bond together, the atoms share valence electrons and do not become […]
