I believe that it will be meter. SI unit goes by 10's. what is the sI unit for lengthThe basic SI unit of length is meter.the basic si unit of lenght is metric.The SI base unit for length is meter. For temperature, the SI base unit is kelvin.
The following instruments can all be involved in a measurement of electrical signals, depending on whether the signal is in wire or in the air, and depending on which of its properties and characteristics you want to measure: -- AC voltmeter -- AC ammeter -- power meter -- frequency counter -- field strength meter -- BER counter
Meter Standard meter is the bar of an alloy of platinum and iridium kept under controlled conditions at the " International Sureau of Weights and Measures" near paris.
REMOVE SOME LOAD LoL
for a disc type (electromechanical) meter the number of disc revolutions to indicate 1 kwh would be found by the formula 1000/ Kh, the watthour constant of the meter.
A standard test current for a Class 10 watthour meter typically ranges from 0.5 A to 5 A, depending on the specific design and application of the meter. This current level is used to evaluate the meter's accuracy and performance under load conditions. Class 10 meters are designed for certain accuracy standards, ensuring they can measure energy consumption reliably in residential and commercial settings. Testing at this current helps validate the meter's calibration and functional integrity.
A "multimeter" to test resistances, voltages, amperages. An external "clamp" meter to measure high ac currents. A "mega" meter to test insulation.
A meter already is the basic unit.
