How do you calculate the multiplication factor of energy meters?
Atulppai7
Look for the ct (current transformer). You will find a ratio rating (for example, 200:5.) This means divide 200 by 5. The result is 40. Any difference in reading from a certain time should be multiplied by 40 to get actual energy consumption. This is the basic information, but in practice it should be calibrated by a government-certified body (the department of energy, for example) to perfectly match the kwhr-meter revolution.

What reasons are there to want to correct a lagging power factor?
When you have a lagging power factor, measuring instruments (i.e. AC energy meters etc..) will read high. For example, if you've actually used 12W, when a lagging power factor is present, the meter might read 13~14W.
How is the power factor meter connected?
power factor meters are connected across the supply
How does power factor affect your power bill?
A poor power factor causes the meter to rotate more slowly than it should, so a poor power factor would reduce your bill. Electric utilities compensate for this in commercial services by billing based on power factor, or they install a meter that actually measures power factor.AnswerEnergy meters 'read' the in-phase component of load current (therefore the load's 'true power' multiplied by time) and, so, are completely unaffected by the power factor of a load. So the power factor of a residential load will have absolutely no effect whatsoever on that residence's 'energy' (not 'power') bill.Industrial and commercial consumers are billed for 'demand' (their rate of consumption of energy -i.e. the power) as well as energy supplied'. In addition, these consumers are usually penalised if the power factor of their load falls below an agreed value. So power factor does affect the overall bill (but not the energy bill) of industrial consumers.

How do you calculate the power consumption in a factory can you give me an idea?
its consist of 2 meters 1 is main meter 2 is check meter , actually this consumption was depend on CT, PT's and by this can find out multiplication factor (M.F).consumption = (check meter reading KWH)*M.F ------1Ex for M.F cal: system-C.T=200/1A, P.T=132Kv/110V,Load- C.T=100/1A, P.T=132Kv/110v.M.F=System C.T*P.T/Load C.T*P.Tthere fore (200/1*132/110)/(100/1*132/110) = 2.-------2Sub 2 in 1 then u got consumption.

1-kg brick is lifted to a height of 30 meters and then dropped How much potential energy remains after 2 seconds of freefall?
Use one of the formulas for constant acceleration to calculate how many meters the brick will fall after 2 seconds. Subtract this from the 30 meters, to see how high the brick is above ground. Finally, use the formula for potential energy: PE = mgh, to calculate the potential energy.

You can calculate gravitational potential energy by using the equation?
PE = mgh (potential energy = mass x gravity x height). In SI units, mass would be in kilograms, gravity (on Earth) is 9.8 meters/second2, and height is in meters. The resulting energy is in Joules.
