This page provides basic knowledge about electric current as well as an easy-to-understand introduction to topics like the difference between current and voltage, different types of current, and methods for mea
A galvanometer is an absolute instrument; it measures the electric current in terms of a tangent of deflection angle. A galvanometer can measure the electric current directly, but this involves breaking the circuit; hence sometimes, it is inconvenient. How Does an Electric Current Produce a Magne...
That’s why your electric bill will be given in kilowatt-hours (kWh). Why do we measure power? Measuring voltage and current is only the initial step to analyzing an electrical system, and can easily be done with any power analyzer or power meter on the market. But in order to manage...
DSF-means three-phase three-wire mechanical multi-rate watt-hour meter, DXF--represents a three-phase mechanical reactive multi-rate watt-hour meter, DDS-stands for single-phase electronic watt-hour meter, DD-stands for single-phase mechanical watt-hour meter. DT862 is a three-phase four-wire...
When your solar panels produce more electricity than you're using at any point during the day, the electricity is sent back to the grid, running your electric meter in reverse. When your energy use is higher than your solar panel production (either at night or on cloudy days), you'll pu...

So many people waste content marketing on self-promotion and uninteresting content, instead of offering materials that are funny, informative, and worthwhile. Many people fail to address the concern: what do people actually want? What does my customer base really need? I see many en...

To prevent a population from shrinking as a result of declining birth rates, the reproductive period should grow in line with energy consumption. But whereas the elephantine creature with theenergy consumptionof a mean German woman could still have children at the age of 70, German women typically...
The value is often used as a comparison between electrical systems. Two systems that operate in the same way with the same power requirement may have different factors. If one system has a higher factor, the lower system has a problem present in either the electrical system or power delivery...
