What is Ammeter explain with diagram? An ammeter (from ampere meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters. What is meant by […]
Which device is used to indicate the direction of current?
Which device is used to indicate the direction of current? The current flows through the ammeter. Note that an ammeter has a very low resistance. How can a DMM be used to determine the direction of flow? When using a multimeter to measure current, the only way that can be used to detect the level […]
Can Atom survive without electron?
Can Atom survive without electron? Electrically neutral atoms can exist with no electrons. So an atom can’t have no electrons as it, by definition has protons and to be neutral must have electrons. You can have an ion, such as a hydrogen ion (you might call it a proton). What would happen if an atom […]
Is anything in retrograde right now 2020?
Is anything in retrograde right now 2020? This is just an optical illusion. Hence the planets appear to stop, go backward referred to as retrograde, stop again and go forward called as Direct motion….Mercury. Direction Retrograde From Oct 14, 2020 11° To Nov 3, 2020 25° What sign is Pluto in today? Scorpio What is […]
What is the minimum velocity needed to transport a cobble?
What is the minimum velocity needed to transport a cobble? At 10 cm per second [?] is eroded whilst would be deposited. Cobbles are upwards of 170cm per second. Deposition starts to occur at cm per second for particles of approximately 0.01mm in size. Boulders require the smallest velocity for deposition, at only cm per […]
What is the minimum ceiling for VFR flight?
What is the minimum ceiling for VFR flight? IFR means a ceiling less than 1,000 feet AGL and/or visibility less than three miles. Low IFR (LIFR) is a sub-category of IFR. VFR means a ceiling greater than 3,000 feet AGL and visibility greater than five miles. What is the minimum VFR? Basic VFR Weather Minimums […]
How much HF is lethal?
How much HF is lethal? Hydrofluoric acid is one of the strongest acids known that has a strong lipophilic ability. Ingestions of more than 20 mg/kg body weight are considered a lethal dose. Even after dermal exposure, the fatal prognosis is caused by severe electrolyte disturbances, especially hypocalcemia. What does an HF burn feel like? […]
Will a 220v bulb work on 120V?
What are 3 organisms?
What are 3 organisms? Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea. What are the 8 organisms? There are different types of organisms, including -producers, consumers, herbivores, carnivores, omnivores, scavengers, parasites, predators, and decomposers. What type of organisms are humans? […]
What prevents the wrong gas from being connected to the equipment?
What prevents the wrong gas from being connected to the equipment? The connection is marked with a Compressed Gas Association (CGA) number and will be left-hand or right-hand threaded to match the nut or fitting. This prevents a piece of incompatible gas equipment from being connected to the wrong gas supply. Can gas cylinders explode? […]
