meter movements are polarity-sensitive, one direction of current driving the needle to the right and the other driving it to the left. Some meter movements have a needle that is spring-centered in the middle of the scale sweep instead of to the left, thus enabling measurements of either ...
Electricity is easy to visualize if you think of it as the flow of water in a river (See Fig.1). Particles called electrons come together, and the number of electrons flowing each second is the current. Difference between voltage and current Voltage is another term that’s used in regards...
Electricity: The electricity we use every day is actually made of electrons, the negatively-charged particles that orbit atoms. Electrical current is the flow of such electrons through a conductor, a substance that allows electrons to flow freely, such as the copper in wires. ...
A smart meter is a type of energy meter that sends automatic gas and electricity readings to energy suppliers to ensure more accurate bills. They replace manual meters, which require you to take your own meter readings and submit them to your supplier. Smart meters also come with an in-home...
What is an impedance meter? Impedance basics and key measurement considerations Overview Impedance, a measure of the resistance in an alternating current (AC) circuit, is not visible. Consequently, it must be measured with a dedicated instrument known as an impedance meter. If you’ve never used...
Meter definition: In the context of American English, ameteris a unit of length in the metric system equivalent to 100 centimeters. Ameteris also a device that records the amount of a substance used, such as electricity, water, or gas. ...

But the reliability is poor and the accuracy is low, cannot satisfy each profession to the electricity demand, has optimized the production induction and the electronic type two kinds of different working principle electric energy meter, and has the security and stability, the...
What is the principle of a galvanometer? What are three ways in which voltage can be induced in a wire? What is the unit used for thermal conductivity? What is the R-factor of insulation and what does it equal? 1) What is meant by the expression "I^2R losses" in electric circuits...
The reading obtained by a current meter is useful in several ways. By measuring current, it is often possible to determine if a circuit is operating correctly. The measurement can tell if enough electricity is flowing, or if there may be a problem with the power source. If current is measu...
