What is the main advantages of using a fuse?
What is the main advantages of using a fuse? 1) It is the cheapest form of protection. 2) It doesn’t need any maintenance . 3) Its operation is completely automatic and requires less time as compared to circuit breakers. 4) The smaller sizes of fuse element impose a current limiting effect under short-circuit conditions. What […]
Where is the magnetic field in a coiled current carrying wire the strongest?
Where is the magnetic field in a coiled current carrying wire the strongest? The magnetic field is strongest inside the coil. This is because the effects of both sides of the vertical part of the wires add up at the centre. What are the advantages of electromagnet over permanent magnet? The main advantage of an […]
What is the resistance across A and B in the Fig 1 point?
What is the resistance across A and B in the Fig 1 point? ⟹ RAB=4+44×4=2Ω What is the total resistance between points A and point B given below circuit? Therefore, the total resistance in the circuit is 4+4+2=10 ohms. What is resistance between A and B? The three resistance of 20 ohm, 10 ohm and […]
How do the kidneys respond to acidosis?
How do the kidneys respond to acidosis? The kidneys respond to acid-base disturbances by modulating both renal acid excretion and renal bicarbonate excretion. These processes are coordinated to return the extracellular fluid pH, and thus blood pH, to normal following a derangement. What can the kidney do to compensate for acidosis? Renal compensation of respiratory […]
Do gravitons have mass?
Do gravitons have mass? Gravitons do indeed have mass, and their motions generate kinetic energy. Other particles have mass, but they are much larger, much less numerous, and cannot substitute for the gravitational effects which generate space curvature. The great mystery of so-called force at a distance is explained by the mass of gravitons. Are […]
Can you go blind from astigmatism?
Can you go blind from astigmatism? Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause […]
What is difference between FID and tcD detector?
What is difference between FID and tcD detector? the basic principle of FiD is the ionization of organic compound by burning the compounds in the hydrogen air flame. Meanwhile, the detection of compound by tcD is based on the difference of thermal conductivity properties between the carrier gas and the target being detected. What does […]
