Why electric flux is zero in a closed surface?
Why electric flux is zero in a closed surface? If there is no net charge within a closed surface, every field line directed into the surface continues through the interior and is directed outward elsewhere on the surface. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric […]
How much power does wind generate?
How much power does wind generate? How much energy do they generate? When the wind is blowing more than 12 miles per hour, each wind turbine can produce 1.5 megawatts of electricity. At reduced wind speeds, electricity production decreases. When wind speed exceeds 45 miles per hour the turbines shut down to protect the machinery […]

What is balancing a centrifuge and why is it important?
What is balancing a centrifuge and why is it important? Why Balancing Your Laboratory Centrifuge Matters Out of balance loading causes the moving parts to shake uncontrollably. At best, this means the motor and bearings wear out more quickly. At worst, it risks sudden and explosive failure of the motor or rotor, and serious injury […]

What is the difference between slip rings and split rings?
What is the difference between slip rings and split rings? What is the difference between a split-ring and a slip-ring commutator? A split-ring makes the current change direction every half-rotation, whereas a slip-ring commutator merely maintains a connection between the moving rotor and the stationary stator. Which device uses slip rings? Slip rings are used […]

What is the ideal atmospheric pressure?
What is the ideal atmospheric pressure? Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals. Why don’t you feel the pressure exerted by the atmosphere? The reason we can’t feel it is […]
