wattmeter उदाहरण वाक्य

The current coils are connected in analog wattmeters, the potential coil carries a needle that moves over a scale to indicate the measurement.
An instrument which measures electrical energy in watt hours ( electricity meter or energy analyser ) is essentially a wattmeter which accumulates or averages readings.
This transceiver unit costs a lot, $ 2000, but includes a neighborhood spectrum analyzer; or you can use a cheaper but less-interesting Wattmeter display.
You will need to use a wattmeter or monitor the AC input .-- Hans Haase ( g�T ) 20 : 31, 23 April 2015 ( UTC)
The "'wattmeter "'is an instrument for measuring the electric power ( or the supply rate of electrical energy ) in watts of any given circuit.

Thus, a circuit with a low power factor will give a low reading on the wattmeter, even when both of its circuits are loaded to the maximum safety limit.
In most types, unlike voltmeters and wattmeters, there is no restoring spring torque for the magnetically produced torques to overcome; the pointer system is free to rotate continually.
A Model 43 wattmeter was used to test the power output of the two-way mobile radio transmitter and to match it to an antenna most commonly mounted on the trunk.
The power factor in a single-phase circuit ( or balanced three-phase circuit ) can be measured with the wattmeter-ammeter-voltmeter method, where the power in watts is divided by the product of measured voltage and current.
Unique features such as the " Fast Responding Wattmeter " and the patented " Power Guard " circuitry set their amplifiers apart from others'products; various models were available offering from 75 to 2000 watts, divided amongst one to six channels.
