What else can I help you with?
What happens when you connect a low current device to a high current source?
The High current source otherwise known as the supply, can handle any low current device or low current load as long as the voltages are the same. The higher the Supply current or as you call the source the better for any device/load
Why does the current decrease when frequency increases?
That depends on actual circuit impedances and without knowing them cannot be answered in any way. But if all the circuit impedances are purely resistive, there will be no change in current flow with any change in frequency.
What is the frequency of a 440 volt electrical supply?
The frequency of any alternating current (ac) electrical supply always depends on the frequency at which the supply has been generated.That is true no matter whether it was generated at a power station, for use in a home or factory, or in a dc-to-ac power inverter unit, for use in, say, a vehicle or boat.Power stations in USA, Canada and other countries generate ac at 60 Hz.Power stations in countries in Europe and other world areas generate ac at 50 Hz."Hz" is short for "hertz" which is the name used internationally for "one cycle per second".
What is the frequency of DC signal?
Zero = Nothing = Nil = 0 Hertz or Cycles per Second Direct Current is just as its name says: it does not alternate so it does not have any "frequency".
How you check the quality of supply voltage?
You need to assess the frequency, amplitude and see if there is any distortion in the waveform. The best way is with an Oscilloscope.
Have any relation with kilowatt and hertz?
Kilowatts measure power, while Hertz measure frequency. They are related in electrical systems because the frequency of the alternating current (AC) power supply determines how often the direction of current flow changes per second. The power output of an electrical device, measured in kilowatts, depends on both the voltage and current frequency.
What is frequence of dc supply?
Zero = Nothing = Nil = 0 Hertz or Cycles per Second Direct Current is just as its name says: it does not alternate so it does not have any "frequency".

What is a direct current circuits?
it is the circuit in which there wont be any frequency and the load is pure resisitive
Why does the current decrease when frequency increases?
That depends on actual circuit impedances and without knowing them cannot be answered in any way. But if all the circuit impedances are purely resistive, there will be no change in current flow with any change in frequency.
Is there any current at the input port of a ups if it is not connected to the main supply and the ups is on?
No, not at all. It will have current when it is charging only

Do you add electrical supply voltage and induced voltage of a coil to get total voltage on the coil?
The induced voltage acts to oppose any change in current that is causing it. So, if the current is increasing, then the induced voltage will act in the opposite direction to the supply voltage; if the current is decreasing, then the induced voltage will act in the same direction as the supply voltage.
What is reactance of electric cable?
'Reactance' is the name given to the opposition to the flow of alternating current, due to the inductance of a load and the frequency of the supply voltage. It is measured in ohms.
What will happen if use a 12v 500ma instead of 12v 300ma?
Using a 12V 500mA power supply instead of a 12V 300mA power supply will likely be fine as long as the voltage matches, but the higher current capacity (500mA) means the power supply can deliver more current if needed by the device. The device will only draw the current it needs, so having a higher current capacity power supply should not cause any issues.
