Q-meter works on the principle of Series Resonance
CLAMP METER WORKS WITH THE PRINCIPLE OF HALL EFFECT..
The working principle of an electronic energy meter is a device that measures the electronic energy consumed (usually in KWh). It is often incased in glass and has a disk that rotates that measures the amount of power (product of current and voltage) the flows through the meter. The rotation is then integrated over time either by mechanical dials or an electronic digital counter to determine the total energy used.To simplify reading, many modern ones also contain a type of radio transponder that can be interrogated remotely from the meter reader's vehicle so he/she no longer has to find, read, and write down the value on every meter on his route.
convert mechanical energy to electrical energy
this is good to know that there is a way i can find somthing usuful for mi studies
trivector meters are used to measure kVAh and also kVA of maximum demand.it has a kwh meter and reactive kvah meter in a case with special summator mounted between them.
basic principle of analogue clamp meter
What is the working principle of venturimeter?
effect of moisture content on solid waste energy determination and principle of bomb calorie meter??
It is a radial flow axial turbine . It works on the principle to convert pressure energy into kinetic energy.
because working principle of both the things are same.The motor converts electrical energy in to mechanical via magnetic induction and generator do the exact opposite of this.And yes,you should use 'electricity generator' not only 'generator'.
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
