Ohm's law says that in an electrical circuit, the current passing through a resistor between two points, is related to the voltage difference between the two points, and inversely related to the electrical resistance between the two points. This relation is shown in the following pee Where I ...
In electricalconductors, current flows as a result of electrons jumping from atom to atom as they move from negative to positive electricpoles. In semiconductor materials, current also results from electron movement, however, the movement is based on electron deficiencies in atoms. An electron-defici...
The working principle of ohmmeter is, it comprises of a needle and two test leads. The needle deflection can be controlled withthe batterycurrent. Initially, the two test leads of the meter can be shorted together to calculate the resistance of anelectrical circuit. Once the two leads ofthe ...
@chivebasil - You are right that the multimeter is an incredible tool. I love the way it incorporates multiple tools into one, but even more than that I like how it improves on the functionality of some of the classical electrical tools. ...
featuring iron jaws that intensify the magnetic field around the conductor. They also use a Hall Effect sensor that converts this field into an electrical signal. Key to their accuracy is the process of zeroing, which compensates for external magnetic influences, ensuring precise current measurements...
How Does an Ultrasonic Flow Meter Work? Ultrasonic flow meter technology is a non-contact means of measuring the velocity of a fluid. They are clamp-on devices that attach to the exterior of the pipe (and fit a variety of pipe sizes) and enable measurement of corrosive liquids without damag...
The Watt-Hour Meter is often referred to as an energy meter or electric meter or electricity meter, or electrical meter. Mainly the watt-hour meter comprises a tiny motor and a counter. The motor will operate by diverting the exact fraction ofcurrentflowing in the circuit to be measured. ...
What is an Auto-ranging Multimeter?Knowledge Base maintenance, multimeters 2 Comments Auto-ranging multimeters have a great advantage for users, as they save the struggle or hassle of having to know the ideal or correct range for measuring whichever electrical value one needs to measure, be it ...
Electrical maintenance is the upkeep and preservation of equipment and systems that supply electricity to a building. The main...
A phase meter is a diagnostic tool that is used to detect electrical waves being transmitted through a power source, and it measures the overall delivery of electricity. These devices run continuously, measuring both voltage and the ensuing current being supplied to anyelectrical circuitto provide ...
