Electric motors are electromechanical machines that convert electric energy into mechanical energy through a spinning shaft. Despite differences in size and type, most electric motors work based on the same basic principle: an electric current flowing through a wire coil in a magnetic field (stator) ...
This paper attempts to link the formerly separate worlds of instrument engineering and electric power metering. It lists key concepts required by instrument personnel to use electric power metering systems with the same ease and skill that they apply to temperature, pressure, level, and flow ...
The electrical current is the intensity or rate of flow of an electric charge. Similar to measuring the voltage, we sometimes need to measure very tiny currents, i.e., in the microamp range, while other times we may need to measure very high currents into the thousands of amperes. AC ...
What is Power Factor Correction (PFC) - Does it help conserve energy? Issue: What is Power Factor Correction (PFC) - Does it help conserve energy? Answer: Explanation 1: Power Factor Correction (PFC) doesn't directly reduce the overall electric consumption of a device or system, but it do...
Let's say that you turn on the space heater and then look at the power meter outside. The meter's purpose is to measure the amount of electricity flowing into your house so that the power company can bill you for it. Let's assume -- we know it's unlikely -- that nothing else in...
The strangler fig pattern provides a roadmap for migration, but not every project is an ideal candidate for the pattern. While it is typically associated with updating legacy applications and transitioning monoliths into microservices, here are some additional factors to consider when determining whether...

This factor is harder to measure than the others, but your joy and comfort certainly have value. If only Netflix offers your go-to show for relaxing after a hard day, or the movies that both you and your kid enjoys, that matters. Whether you realize that Netflix provides this kind of...
But there's a simple way to measure magnetism with a device called a Hall-effect sensor or probe, which uses a clever bit of science discovered in 1879 by American physicist Edwin H. Hall (1855–1938). Hall's work was ingenious and years ahead of its time—20 years before the ...
Solar panels and electric vehicle charging could be a useful pairing. SimonSkafar/Getty Images Why knowing your payback period is important Now you have your solar payback period. How does that factor into your decision? "It depends on what is motivating the household to make the decision to...
