If you know the kilovolt-amps and power factor (PF)of a generator, UPS, or battery power source, converting kVa to kilowatts is easy.Here’s the formula:kVa × pf = kilowattsFor example, a 5kVa generator with a power factor of 0.8 will have an AC or DC output of 4000W (4kW)....
In physics, electric power is the rate of doing work. It is equivalent to the amount of energy consumed per unit of time. The unit for power is Joule per second (J/s), also known as Watt (W). What is electrical power Electrical power is the rate per unit of time that electrical ...

Can you describe any (real physics) setup, where two photons exactly annihilate into the vacuum? If so, something's wrong in your calculation, because energy-momentum conservation holds, and the vacuum state is the state of lowest possible energy, i.e., the ground state, and any two-...
The fraction of energy reflected is A[(X−1)X]2 B[X/(X+1)]2 C[(X−1)/(X+1)]2 D[1/X]2Submit In a stationary wave pattern that forms as a result of reflection pf waves from an obstacle the ratio of the amplitude at an antinode and a node is β=1.5. What percentage...
Capacitance is a fundamental concept in electrical engineering and physics, describing the ability of a system to store energy in the form of an electrical charge. It is a property of a system in which an insulating material, or dielectric, separates two conductive plates. Capacitance is a cruci...

What are the principles of physics that govern biological processes or systems? What are some salient examples where systems biology has helped explain a complex process? What are the characteristics and functions of human Nervous System? What is the role of the nervous system? What branch of bio...
The same form of equation for resistors in series, which can be confusing unless you think about the physics of what is happening. The capacitance of a series connection is lower than any capacitor because for a given voltage across the entire group, there will be less charge on each plate...
