component (Ip)‚ and a reactive component (Ir). Because of the way these are related‚ the total current is calculated as follows: And since the Pf is calculated as kW/kVA then the formula below can be used. VIp is the real power‚ measured in watts‚ while VIr is the reactive power‚ measured in vars (volt-amps reactive). At the end of a measuring period‚ the average power factor is calculated as follows: Some equipment draws current that is heavily distorted from the ideal sine wave.

Metering Formula 1. Meter Multiplier Meter Multiplier - the multiplier applied to the register reading to obtain kilowatt-hours. M = Kh X Rr X Rs X CTR X VTR 10‚000 Where ; Kh = watt-hour constant of the meter in watt-hour per revolution Rr = register ratio = the number of revolutions of the register worm wheel for a revolution of the first dial pointer (right hand). Rs = gear ratio = the number of revolution of the disk for one revolution of the first point CTR = current transformer

(Source: Canadian Centre for Energy Information compilation‚ 2013) There are now 3‚133 megawatts of solar power installed in the U.S. That’s enough to power nearly 3 million homes. The average cost of solar power fell 27%‚ from $4.10 per watt in 2011 to $3.01 per watt in 2012. The solar industry grew 76% in 2012 alone. A single Air Force base in Nevada has saved $83‚000 A MONTH since it switched from using traditional energy sources to solar energy produced on site. You can lease your property (such

People have rioted against Uncle Sam‚ like the South during the Civil War and to some the Ferguson rioters. Often times people riot only because they feel they are unheard by their government and only want solutions to their problems. Riots have long been a part of American history‚ America itself was birthed from a riot against the tyrannical British power. How can a nation be calm when schools are terrorized‚ people of color are murdered by police officers with no consequences

We don’t know the reason for the riots‚ but it’s pretty heavy. They’re shooting different kind of weapons at each other and it’s quite dangerous. The riots in streets could be a symbol for Laura’s life where the mob is the part of her that wants to leave her husband‚ but are also the weakest in a fight against the police that would be her fear

Solar Cell Practical Report 2011 Aim: To find the amount of power generated from a solar cell with a light bulb by using a multimeter. Hypothesis: The further you move the solar cell away from the light bulb the less power will be produced. Backup statement: I can support my hypothesis through my own given knowledge on power and electricity. I can comprehend the facts that‚ if the Light Bulb was generating a large amount of heat and light‚ the solar panel
