The following method assumes that you know how many amps you need for the gadget under power. If you know the watts go to Step A below. Step 1. Back of the envelope If the current drawn is x amps, the time is T
Use the equation listed in the graphic above to deduce exactly how many amps your home needs. How to Add Capacity to Your Electrical Load Installing a new circuit is not difficult, but before you begin, make sure your service panel can handle the extra load. A service panel with too ...
11. How to Calculate Recommended Lighting Levels for Office & Computer Work Lastly, let’s look at how to calculate lighting levels in your office and computer work. The calculations here are also very elementary. Basically, this method will involve calculating the number of watts needed for lig...
Amperage I amps Resistance R ohms V = I × R I = V / R R = V / I Electric power P = I× V (Power law PIV) Electric power = amperage × voltage (Watt's Law) Please enter two values, the third value will be calculated. Electric Power P watts Amperage I amps Voltage V ...
Horsepower is a measure of power, and voltage measures the amount of energy carried in a circuit. Current, measured in amps, represents how fast the energy moves through a circuit. For example, you might use horsepower and voltage to find the current in a motor. In order to calculate the...
Well - just reduce your argument as far as you can and explain how the MPT suddenly ceases to apply. How many reactances are needed and where would you say they need to be placed? Could you just put in a few and reduce the consequences of the MPT by ' just a bit'. You would...
You can calculate kilo-volt-amps (KVA) from three-phase kilowatt (KW) by following a formula. This formula can be used for information regarding industrial motors and home emergency generators, provided you know the power factor. Alternatively, the power factor can be measured by finding the di...

Using spreadsheets to calculate errors can save valuable time, particularly when changes are needed. Figure 6 shows a spreadsheet used to calculate total error based on worst-case errors pulled from the data sheet. The root sum of squares (RSS) analysis, where total error is ...
How do I add the Air Conditioning units? Are they linear or non? I only know the ton value of each. And, What is the correct connection for single phase ACs and lights? Is it Y-D? I also have a three phase 60 HP submersible pump that sucks 150 Amps on each phase to start and...
