Power equals the product of current and voltage. The power used by a 9 amp 27 volt circuit is 243 watts. The power produced by the device, however, depends on the device's efficiency.
A 'volt ampere' (not 'volt amp'!) is the unit for theapparent power of a load in an a.c. circuit. It is simply the product of the supply voltage and the load current.
No, that is too much.
The current will remain in a 220 volt circuit as long as the circuit load remains in the circuit and the circuit remains closed.
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
The formula you are looking for is W = I x E.
The cost is about the same using the equation Power= Voltage X Current . However , if the 115 volt electrical circuit is produced from a 230v supply though a transformer , then the transfomer incurs loses and therefore the cost is greater .
A volt meter will do the job.
It depends on the use it is being put to. It is sufficient for a 24 volt circuit. Too much for a 12 volt circuit and too little for a 240 volt circuit.
A volt can not be connected to a circuit.
That would depend on the power output (watts) of the circuit. Volts times the Amperage equals the Wattage of the circuit. You do not have enough information in your question. Volts is the force applied to move the electrons in the circuit, and amps are a measure of the quantity of electrons moved through the circuit over time. Thus a circuit of 415 volts and 1 ampere will deliver 415 watt-hours of power. Yet a circuit of 1 volt at 415 amps will deliver the same 415 watt-hours of power, but with less force.
It depends on how much power the lamps require, and on how they are connected.
A 'volt ampere' (not 'volt amp'!) is the unit for theapparent power of a load in an a.c. circuit. It is simply the product of the supply voltage and the load current.
+12 volt , -12 volt, + 5 volt, - 5 volt, and + 3.3 volt.
Power = voltage x currentCurrent = power/voltage = 12/120 = 0.1 ampere = 100 milliamperes
Yes. Power in both cases is 1.035 KW. Your meter shouldn't know the difference.
No, that is too much.
The current will remain in a 220 volt circuit as long as the circuit load remains in the circuit and the circuit remains closed.
