The power of magnification is calculated by dividing the focal length of the objective lens by the focal length of the eyepiece lens in a microscope or telescope. The formula is: Magnification = Focal Length of Objective Lens / Focal Length of Eyepiece Lens. For example, if the objective lens has a focal length of 10 mm and the eyepiece lens has a focal length of 25 mm, the magnification would be 10/25 = 0.4x. Additionally, in microscopy, total magnification can also be determined by multiplying the magnification of the objective lens by that of the eyepiece lens.
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
output power/Rated power
If a load takes 50 kW at a power factor of 0.5 lagging calculate the apparent power and reactive power Answer: Apparent power = Active power / Power Factor In this case, Active power = 50 kW and power factor = 0.5 So Apparent power = 50/0.5 = 100 KVA

Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
How do you calculate 3ph AC motor power?
To be able to calculate a mi to the second power you need to
You can't "calculate" it...
If you know the power you do not need to calculate it by anything. And if you don't, the answer will depend on what measure you do know!
If you have 3 to the power 2 to the power 2, without any parentheses, you have to calculate from right to left. In this case, calculate 2 to the power 2; then calculate 3 to the power (whatever the result you get). If there are parentheses, do the calculation in parentheses first.
This calculation will give you the ratio, in decibels, between two power values. For example, you can calculate the difference in dB between two amplifiers with different power output specifications calculate in dB Power Ratio.
Usually there is not.
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
Power = Work/Time Time = Work/Power Work = Power * Time See related links for a power calculator. Insert work and time to calculate power.
