Power Factor Calculator It is used to calculate the apparent power, power factor, correction capacitor's capacitance and the reactive power. The result, measured in watts, is the amount of power your LEDs use. I do not have access to many calculators, but I can give some answers. Scientific Calculator. Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts). Online exponent calculator - easily compute the power of a given base, raised by a given exponent. Calculate any Power of i (the Square Root of -1) When learning about imaginary numbers, you frequently need to figure out how to raise i to any power. When you begin using anything from simple filters, time intelligence functions or even advanced formulas, often the CALCULATE formulas are leveraged to produce the desired outcome. Step 1: Getting the power information for your appliances For example, if you have a 0.85 power factor, 1.5 kW of power and a voltage of 230 V, simply quote your power as 1,500 W and calculate: Bike Calculator is an engineering model - that is, you feed it relevant parameters, and it makes predictions about the system.

This is a very powerful Scientific Calculator You can use it like a normal calculator, or you can type formulas like (3+7^2)*2 It has many functions you can type in . It goes hand-in-hand with sample size. Calculate Electricity Usage. The system is you - the engine - supplying the power to resist the three major forces involved in cycling - gravity, rolling resistance and aerodynamic resistance. Application of exponentiation in economics, physics, biology, marketing. DC power calculator; AC power calculator; Energy & power calculator; DC power calculator. You start by first selecting the phase which may be single or three phase. Thank you to Dr. Daniel Deligio and the GP Lens Institute for requesting this calculator.. Of course some power … Allowing you to calculate the electrical cost of your home appliances, and helping you save power consumption costs. During an emergency is not the time to discover your home's wattage needs. If you already understand these terms feel free to skip the following section and go use the energy consumption calculator. e^x - Napiers number, e Raised to Power x Calculator. Enter the value of x to find the value of the exponential function e x e is called as Napiers constant and its approximate value is 2.718281828. x is the power value of the exponent e. For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power. Just type your power into the box, and click "Do it!" 2 is the logarithm, also known as the exponent or power 100, 1000 are the numbers Make use of this simple step by step tutorial to learn how to calculate log base 10. Calculating this by hand should only take little bit of time, and I get about $0.40$ (although I did use a calculator). In this calculator/table, you may enter two of the four factors in Ohm's Law. Locate the percentage key.
