power=i square*resistance
or
power=v suare/resistance
Basically VA is the same as watt. Kilo means thousand, Mega (abbreviatted M) means a million.AnswerThe watt and the volt ampere are used to measure two different quantities and, so, cannot be directly converted one to the other. The watt is used to measure 'true power', while the volt ampere is used to measure 'apparent power'.There is, though, a relationship between the two, as the true power of a load is equal to its apparent power multiplied by the power factor of that load. So, if you know the power factor (which can vary from 0 to 1), then you can determine the true power of a load, if you are given its apparent power.Incidentally, SI doesn't recognise either the volt ampere (apparent power) or reactive volt ampere (reactive power); all forms of 'power' are measured in watts in SI. The volt ampere and the reactive volt ampere are best described as 'traditional' units.
The formula for amperage is:I = V / RI = amperage, V = voltage, and R = resistance.Also amperage can be found by using the following formulas.I = P / V, Amps = Watts/VoltsI = sq root P/R, Amps = the square root of (power divided by resistance) watts/ohms.
1/1 = 1ohm MR. volta [italian] Determined that it would take 1 volt to pass 1 amp trough a 1 ohm resistor MR ampere [ french] Ditermined that it would take 1 ohm and 1 volt to pass one ampere MR ohms [english] determinaed that for 1 volt and one ampere the resistance must be 1 ohm. mr watts determined that the product of volts x ampere will equal one watt [power]
Assume the rating of 100W refers to operation on a supply of 117 volts.Power = (voltage) x (current)Current = (power) / (voltage) = 100/117 = 0.855 ampere (rounded)Power = (voltage)2 / (resistance)Resistance = (voltage)2 / (power) = (117)2 / 100 = 136.89 ohms
The volt ampere (V.A) is the unit of measurement of apparent power.Apparent power is the vector sum of a circuit's true power and reactive power.A kV.A (not 'KVA') is the symbol for kilovolt ampere, whereas MV.A (not'MVA') is the symbol for megavolt ampere. So the latter is one-thousand times greater than the former!
The power vs resistance graph illustrates how power output changes with varying levels of resistance in a system. It can be used to analyze the relationship between power and resistance by showing how power increases as resistance decreases, and vice versa. This graph helps in understanding how changes in resistance impact the power output of a system.
A kilowatt is an unit of true power in an AC circuit -as measured by a wattmeter. A kilovolt ampere is an unit of apparent power in an AC circuit, which is the product of the voltage across a load by the current through it. The relationship between the two is: kilowatt = (kilovolt ampere) x (power factor of load)
The relationship between power (P), current (i), and resistance (r) in an electrical circuit is described by the formula P i2 r. This means that power is directly proportional to the square of the current and the resistance in the circuit.
P=I^2*R where P=power I=Current R=Resistance
25kv=?kwAnswerA volt ampere (V.A) is the unit of apparent power, and applies to AC circuits that contain resistance and reactance. Apparent power is the vector sum of true power and reactive power. A kilovolt ampere is 1000 V.A. The volt ampere is the product of supply voltage and load current.
The relationship between power dissipation (P), current (i), and resistance (r) in an electrical circuit is represented by the equation Pi2r. This equation shows that power dissipation is directly proportional to the square of the current and the resistance in the circuit.
An ampere (A) is a unit of electric current, measuring the rate of flow of electric charge. Ohm (Ω) is a unit of electrical resistance, measuring how much a material resists the flow of current. In simple terms, amps measure the flow of electricity, while ohms measure the resistance to that flow.
The relationship between power dissipation (P), current (i), and resistance (r) in an electrical circuit is represented by the equation P i2r. This equation shows that power dissipation is directly proportional to the square of the current and the resistance in the circuit.
Watts (or kilowatts) and amperes are used to measure different things. Watts is a unit of power; ampere is a unit of current. The relationship (for direct current) is: watt = ampere x volt For AC, the relationship is a bit more complicated: watt = ampere x volt x power factor However, the power factor is often close to one.
The resistance of the lamp can be calculated using the formula: Resistance = (Voltage)^2 / Power. Plugging in the values gives: Resistance = (120 V)^2 / 120 W = 120 ohms. So, the resistance of the 120-W incandescent lamp connected to a 120-V power supply is 120 ohms.
Watts is a unit of power, whereas Amperes is a unit of current. They're related though, along with Voltage, Resistance etc. But they're not the same thing, so to answer your question: There are no watts in an ampere! Power (W) = Voltage (V) x Current (I)
The relationship between resistance and temperature in electronic devices is important because as temperature increases, the resistance of the device also increases. This can affect the performance of the device by causing it to consume more power, generate more heat, and potentially lead to malfunctions or failures. It is crucial to consider and manage this relationship to ensure the proper functioning and longevity of electronic devices.
