How does a watt-hour meter work?
There are a couple of kinds of watt-hour meters: one is an electromechanical type (the one with the spinning wheel), and the other is a solid-state type. The solid-state types generally use a current transformer to measure the current produced in the current-carrying conductors, which means that the current carrying conductors need not be connected to the actual measuring device.) The electromechanical type uses an aluminum disc acted upon by two coils. One coil is positioned in such a way as to produce a magnetic flux in proportion to the voltage on the disc, and the other coil produces a magnetic flux proportional to the current. This causes the disc to rotate at a speed proportional to the power (voltage times current) being used. A permanent magnet is also installed in such a way as to exert an opposing force in proportion to the rotating speed of the disc. This causes the disc to slow down and stop when energy stops being used. The aluminum disc is also attached to a worm gear which drives the register.

A watt is the electric unit of power. Amperage x voltage = watt. 746 watts is one horsepower. A wattmeter measures power. Answer A wattmeter measures the voltage app…lied to a circuit, the resulting current , and the cosine of the angle between them , allowing it to indicate the true power of a circuit, in watts, regardless of the nature (resistive, inductive, or capacitive) of its load. Incidentally, the watt is the SI unit for power, it is not the 'electric unit' of power, as there is no such thing as 'electric power'.
A watt meter is what the power suppliers have on the side of your house to monitor the use of electricity going into your home. These can also be bought at electrical wholesal…e suppliers. There is a second kind of watt meter that measures in the RF frequencies. It is connected into the coxial cable on the output side of a transmitter. These can be purchased at radio shops that sell amateur radio equipment. Additional Answer Actually, what you have on the side of your house to monitor your use of electricity is an energy meter , not a wattmeter. Wattmeter are used to measure power . Your electricity meter is used to measure energy, expressed in kilowatt hours.
The Iphone 5C is Iphone 5Colorful 5c can also stand for thenumber 500 ("c" is the Roman numeral for 100) or for 5 degreesCelsius (centigrade) . +++ . "5c" can not stand fo…r any Roman numerals forthree reasons. For a start you do not mix Arabic and Roman numeralslike that - it would be nonsensical. Secondly, the Roman for 100 is capital " C ", but thirdly, in the Romanscale, 5 is V, 50 is L and 500 is D. The ' C ' isalso capital for degrees Celsius / Centigrade.

You don't. Square meter is a unit for area, meter is for length - they're different things.

What is the difference between the watt hour meter and Var hour meter in terms of internal connection and work theory ie When the meter records watt-hour an when the meter records var hours?
Only watts (power) can produce work (energy) because of the phase relationship of the voltage and current in an alternating current, electric power system. With watts, the por…tion of the current and voltage that are in-phase with each other can do work. Vars, on the other hand are volt-amps reactive, which are out-of-phase with each other. Since Vars cannot do work, their existence in the electric power system is parasitic. The reactive current which flows in a power line, for instance uses a portion of line capacity, and also causes heating (I^2 * R power loss) due to the inherent resistance of the conductors. So, in the construction of a simple electromechanical meter, measuring Watt-hours or Var-hours, the respective current and voltage coils used to drive the rotating disk are situated to produce torque. For a Var Hr meter, the coils are rotated 90 degrees relative to each other to counter the lagging or leading phase shift and thus produce torque.
5cc? cc means cubic centimetres which is equal to ml, so 5ml. if you mean cl, then that is equal to 50ml
A mechanical tach will register 1 engine hour for every 100,000 revolutions. At 1666.6 rpm it will register 1 hour for every hour run. At 800 rpm it will take two hours of r…un time to register an hour.. In my opinion this was a more accurate method of measuring engine wear but is rarely used any more.. 10 hours on the tach means your piston went up and down 1 million times..
