Can you convert current to voltage? We usually say that the resistor converts the current IIN into a proportional voltage VOUT or it serves as a simple current-to-voltage converter – a linear circuit with transfer ratio k = VOUT/IIN [V/mA]. A bare resistor can convert current into voltage. How do you convert low current to […]
What is the difference between survival of the fittest and natural selection?
What is the difference between survival of the fittest and natural selection? “Survival of the fittest” is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those […]
Can velocity be zero if acceleration is zero?
Can velocity be zero if acceleration is zero? When acceleration is zero then velocity of object can be zero or constant. The body continues to move with its velocity throughout. For e.g if a train is at rest then acceleration is zero and velocity remains zero. Why does velocity change direction zero? The velocity, that […]
How do I check my Etabs time period?
How do I check my Etabs time period? The time period (the one-story model of the structure is below) calculated manually by using the equation in IS 1893: 2016 is 0.170963 and that given by Etabs 2017 is 0.171 (highlighted in the picture below). How do you calculate time period of vibration? As the frequency […]
What is the application of third law of thermodynamics?
What is the application of third law of thermodynamics? The third law of thermodynamics states that the entropy of a perfect crystal at a temperature of zero Kelvin (absolute zero) is equal to zero. Entropy, denoted by ‘S’, is a measure of the disorder/randomness in a closed system. All the atoms and molecules in the […]
Why is gravity proportional to mass?
Why is gravity proportional to mass? According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons. Most gravitons exist in a cloud around the object. What is the similarities between mass and […]
How is pressure maintained in a reactor?
How is pressure maintained in a reactor? As shown above, mass flow meters are often used to control the input of various gases (and sometimes liquids) into the heated reactor containing the catalyst sample. A back pressure regulator is typically used on the exit of the reactor to maintain stable pressure control for the catalysis […]
What is the best anti-vibration material?
What is the best anti-vibration material? Rubber Where are vibration isolators used? Vibration Isolation Pad Mounts Pads or sheets constructed of flexible materials such as elastomers, rubber, cork, dense foam and laminate materials are often used under heavy machinery, under common household items, in vehicles and other applications to reduce noise and vibration transmission. What […]
Do Low flow shower heads save money?
Do Low flow shower heads save money? Low flow showerheads reduce both water and energy usage, since reducing the amount of water used by the shower will also reduce the amount of energy used to heat it. In doing so, low flow showerheads also reduce the amount of money spent on utilities. Are Low flow […]
