How do you check a buck converter? Step-loads with rise/fall times of 200 ~ 500nsec will be sufficient to test the stability of most buck converters. Figure 2 shows a simple tool to generate fast load steps to a converter : A MOSFET driven by a pulse generator switches a load resistor on and off […]
What makes hydrogen peroxide and water different?
What makes hydrogen peroxide and water different? Its physical properties are very similar to those of water, except that it is 40% denser. The main difference between hydrogen peroxide and water, however, is in its chemical behaviour. The single bond between the two oxygen atoms is weak, so that H2O2 readily fragments into either H […]
How can you tell if a solution is supersaturated?
How can you tell if a solution is supersaturated? Trace the solubility of a substance with increasing temperature. The curved line represents saturation. Below the curve, the solution is unsaturated. Above the curve the solution is supersaturated. This means there is more solute than the solution can hold. How can we prepare a saturated solution? […]
What is an example of sound energy?
What is an example of sound energy? Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal. What is heat energy in simple words? Heat energy is the result of the movement of tiny particles called atoms, molecules […]
How the resistance of a wire depends on its length?
How the resistance of a wire depends on its length? The relationship between resistance and wire length is proportional . The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the […]
How do you calculate H+ concentration?
How do you calculate H+ concentration? Key Concepts The hydrogen ion concentration in a solution, [H+], in mol L-1, can be calculated if the pH of the solution is known. pH is defined as the negative logarithm (to base 10) of the hydrogen ion concentration in mol L-1 pH = -log10[H+] [H+] in mol L-1 […]
What are three differences between latitude and longitude?
What are three differences between latitude and longitude? What is the difference between Latitude and Longitude? Latitude Longitude It is known as parallels It is known as meridians The length of the lines are different The length of the lines are the same It classifies heat zones It classifies time zones There are 180 latitude […]
Which best describes why a diamond ring will sometimes?
Which best describes why a diamond ring will sometimes? Answer Expert Verified. The correct answer should be refraction. Similar things occur with water vapor that gets hit by sun rays after rain. Are alpha waves good? Since alpha waves are linked with relaxed mental states, many experts believe increasing alpha activity may help reduce stress […]
What temperature does 50/50 antifreeze freeze at?
What temperature does 50/50 antifreeze freeze at? BOILING & FREEZING POINTS Pure water, as you may know, has a boiling point of 212°F (100°C) and a freezing point of 32°F (0°C). However, when you create a 50/50 mixture using water and ethylene glycol, the boiling point rises to 223°F (106°C) and the freezing point lowers […]
What will be the equivalent resistance obtained when three resistors of 2 Ohm 4 Ohm and 100 Ohm are in parallel combination?
