it also depends on what meter you have, is it a KWH METER or a AH METER.
IF ITS A KWH METER(KILO WATT HOUR) IT COUNTS IN WATTS (35w PER HOUR.)

They have most of the power.

The problem was that there was too much water so obviously it flooded.
Why was Samuel Adams an antifederalist?
becauseit gave too much power to the national government and less power to the state,the executive branch would have too much power...and...there wasn't a plan for a bill of rights

a lot
What was the supply of oxygen in the great fire of London?
There was as much oxygen as there is outside today which meant the fire could spread much easier than without oxygen
How much voltage do you give to the zero watts bulb?
230v power supply .................it requires 12watts......
When connected to a 110-volt power supply how much current does a light bulb draw when it has a resistance of 220-ohms?
The formulas you are looking for is I = E/R.
What is the power rating of lights?
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
How much power does a 5 watt bulb use?
The bulb uses 5 watts of power.
Can you use 110v chandler in 220v country by changing a 220v light bulb The chandler said max 100w light bulb so do you need to use a smaller watts of a 220v light bulb?
No, changing the light bulb wattage would not convert the chandelier from 110v to 220v. You would need a voltage converter or transformer to safely use a 110v chandelier in a 220v country. As long as the replacement bulb stays within the maximum wattage specified by the chandelier, you can use the original wattage.
How much power does a CFL bulb use in comparison to a standard bulb?
Look at the base. The power rating will be printed there.
Can I combine 2 110v 15 amp outlets on a generator to power a single 30 amp 110v outlet on my boat?
No, you cannot combine two 15 amp outlets to power a single 30 amp outlet. The 30 amp outlet requires a dedicated 30 amp circuit to function properly. Combining the two 15 amp outlets will not provide the necessary power and could lead to electrical hazards.
How much electricity does electric bulb uses?
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
Which is more powerful 110v or 220v?
"Power" is not expressed in volts, but rather in watts (Volts times Amperes), for instance. So you cannot say whether 110v or 220v is more Power-ful unless you also know how much current (Amperes) is flowing in the electrical circuit.
Can you use 110v 60Hz supply for 110v 50Hz equipment?
If the load is non inductive and straight resistive then there is no problem. Inductive loads like motors, a 60 Hz device can be used on 50 Hz but it is much harder on the equipment if 50 Hz is used on a 60 Hz system.
What would be the voltmeter reading if the lamp across which it is placed has a broken filament?
A voltmeter connected across the broken (open) filament of a light bulb reads the full voltage of the power supply whether the bulb is in a series or parallel circuit. -- In a series circuit with other components in series with the bulb, this reading tells you that at least one of the components is open, possibly the filament. -- In a parallel circuit with other components in parallel with the bulb, or with the bulb connected directly to the power supply, this reading tells you nothing ... the voltmeter reads the full power supply voltage whether the bulb is open or good. The voltmeter isn't a very helpful measurement to identify an open filament. An ohmmeter, with the power to the circuit turned off, is much more helpful.
How many cables are supplied by the power supply?
as much as you can
