When voltage increase then current will be?
it depends on what type of load. Motor amperage will drop off as voltage rises. loads such as lights will increase amperage with voltage rise.
How much percentage of current takes motor runs at no load?
The FLA of a motor is the amperage that the motor operates at. So to answer the question, 100%.
What does LRA mean in electrical terms?
Locked rotor amperage is the amperage the motor draws when the voltage is first applied to the motor and the rotor has not started to turn. This amperage is usually up to 300% of the motors running amperage. Once the rotor starts to turn the motor generates a back EMF (electro motive force) that opposes the high inrush current. This back EMF drives the amperage down until the motor gets up to its rated speed at which time the motor amperage will be at its run amperage.
Can you reduce amperage by using thicker wire with a constant voltage?
The amperage flowing through a wire is directly related to the load placed on the circuit, and has nothing to do with wire size, except that a larger wire will carry more amperage. Increasing wire size will not lower amperage but will allow the circuit to carry more amperage if the breaker is also increased in size. No. Ohm's law tells us that V = IR. For a given load, R is constant, and thus the only way to reduce current is to increase voltage.
When does a motor draw current more than its rated current?
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.
When voltage increase then current will be?
it depends on what type of load. Motor amperage will drop off as voltage rises. loads such as lights will increase amperage with voltage rise.
If my AC technician says my unit is rated at 28.9 amps and drawing 24.8 and should draw about half of rated capacity and that compressor needs to be replaced Is this correct?
There are several amperage ratings on AC compressors/motors. Locked Motor Amperage (LRA) is the amperage that the motor is fused for. The load of the motor is expressed in amperage or wattage, which is probably the case here. Low amperage readings on an AC unit being charged by amperage load would indicate low freon. High amperage readings indicate overcharge when charging by the amperage load. AC units are not accurately charged by amperage readings and the efficiency of motors is not expressed in amperage readings.
What is the amount of current flow through a wire?
The amount of current flowing through a conductor is governed by the amperage of the connected load. This is why there are different sizes of conductors. Each conductor size is only allowed a specific amount of amperage to flow through it. If the amperage load is higher that what the conductor is rated for then the next larger size conductor has to be used. The limiting of the amperage to specific size conductors keeps the conductor from heating beyond the conductors specifications, under full amperage conditions.
How many watts in 20 volts?
You need to have the amperage to determine how many volts you get out of 20 watts.
What would drop the amps on 220 plug?
The amperage on a circuit is governed by the connected load. If a load changes its current draw it can be detected by an amp meter connected to the circuit.
What is current in India I know voltage is 220-240 what is the current in amps?
Current is common throughout the world. The current is based on what the load draws. The equation you are looking for is Amps = Watts/Volts. Other equations for amperage are Amps = Sq root of Watts/Ohms and Amps = Volts/Ohms. So as you can see the amperage is dependant upon the the value of voltage, wattage and resistance.
Which insulated electrical wires match specific Amp loads?
All electrical wires are rated for specific amperage's. This is why conductors are matched to the load current so that a smaller size wire in not used on a heavy load current.
How much percentage of current takes motor runs at no load?
The FLA of a motor is the amperage that the motor operates at. So to answer the question, 100%.
What does LRA mean in electrical terms?

This back EMF drives the amperage down until the motor gets up to its rated speed at which time the motor amperage will be at its run amperage.
What wire size for world's simplest motor?
Wire size is based on the amperage of the load. Without knowing what the motors's full load amperage is, an answer can not be given.
What component in a battery governs current flow?
Current flow is governed by the size of the battery and the load that is applied to the battery By current you are asking for the amperage flow By Danny from Bee Mech Mobile Mechanics Find us at www.beemech.com.au
How do you calculate voltampers in ac circuits?
The volt ampere (V.A) is the unit of measurement for the apparent power of an a.c. load. It is the product of the supply voltage and the load current.
