In the case of a vacuum, the highest load, and thus the highest current, is when the nozzle is free flowing. Lowest current draw is when the nozzle is plugged. If you plug the nozzle with your hand, you will actually hear the motor speed up. This is because it is doing less work (that is, moving air). The vacuum is free spinning (not moving air) when the nozzle is plugged. Check the links section, for a link to a data sheet for an Ametek-Lamb vacuum motor. Notice in the performance curves where the current is maximum (17.4A) when the orifice is 2.0 inches (free flow), and the current is minimum (12.6A) when the orifice is 0.0 inches (nozzle plugged). Also notice how the RPM increases dramatically as the orifice (intake) is plugged. This is opposite of what common sense tells you it should be, but that's the way it is!

Does ballast use amps?
Yes a ballast uses amperage. That is the number beside the letter A on the ballasts nameplate. Depending on the size of the lamp or lamps will govern the size of the amperage that the ballast will draw.
How long will a 10 watt pump run a 12v 70 amp battery?
To answer this question the amperage draw of the motor must be given. This amperage is then divided into the amp hour capacity of the battery to find the endurance time of the motor.
How many amps does a can light use?
The answer depends entirely on the wattage of bulb used! You can find the amperage of your light by using the Power Law which states that amperage = wattage divided by voltage. Thus a 60 watt bulb on a 120 volt system would draw .5 or 1/2 an amp.
Why do you need a 125 amp breaker for a 83 amp furnace?
If you put a 85 amp breaker in there it will overheat from the starting and stopping of the motor. The extra size of the breaker insures that the furnace will run without interruption and without overheating the breaker. And electric motor can draw three times the amperage rated on start up momentarily. This is why there is need of extra amperage ratings.
What size breakers are needed for two 500 watt baseboards?
Each baseboard heater will draw a little over 4 amps at 120 volts or 2 Amps at 240 volts. The total number of baseboards on a circuit will draw the sum of these amps. Keep the load under 80% of the amperage rating of the breaker.
Does an electrical receptacle draw power?
No the receptacle itself does not consume any power it is just a source of power. No amperage is used until the load is plugged in and turned on. Appliances plugged in with the switch in the off position draw no current. Devices that do not have an off- on switch will start drawing power as soon as they are plugged in. Once an appliance is switched on you are billed for the use of the electricity.
What makes a marine battery's terminals hot?
Amperage draw, excessive amperage draw, and or dirty & loose connections. This should be checked out if the temperature is elevated when not cranking your engine.
Why do sparks jump when you pull the plug of a vacuum cleaner but not when you pull the plug of a lamp?
This is due to a higher amperage draw from the vacuum. Where a lamp most likely pulls less than 1/2 amps. The vacuum pulls more as it runs. Therefore the load, or amps, make it harder to break the circuit which causes the sparks
Can using larger wire sizes reduce amp draw?
Using larger wire sizes will not reduce amp draw. The amp draw is determined by the electrical device or load connected to the circuit, not the wire size. Larger wire sizes are used to reduce voltage drop and heat generation in the wiring, but they do not directly affect the amp draw of the circuit.
How many watts does a compact fluorescent bulb draw?
Look for an amperage on the ballast. Multiply this amperage by the connected line voltage. This will give you the wattage of the unit.
Can you run a motor of greater amperage draw with a motor of less amperage draw?
It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.
What is loading rate?
The maximum amperage draw or load that the device or wire can safely carry.
What is circuit amperage?
Generally speaking an appliance (eg tv) is supplied with power so when it is off it has voltage supplied. After yo turn it on it starts to draw power called amperage the voltage doesn't get higheur but the amperage does Amperage is the load being drawn through a circiut
A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes How much current runs through the vacuum?
In this case 4.2 amps of current are running through the vacuum.
What is another word for vacuum or sucktion?
Another word for vacuum or suction is "draw" or "pull."
How much amperage does a 12v LED draw?
Not enough to worry about. That's like asking how many amps does the memory preset's on your radio draw. It is in the .001-.01 range.
Does ballast use amps?
Yes a ballast uses amperage. That is the number beside the letter A on the ballasts nameplate. Depending on the size of the lamp or lamps will govern the size of the amperage that the ballast will draw.
