Hi, the formula used to calculate this is P = U x I.
where:
P = Watt (W)
U = voltage (V)
I = current (A)
You need 2 units to calculate the third one.
Volt x current equals Watt
240 V x 0.1 A (equals 100mA) = 24 Watt
AnswerThe equation for (true) power in an AC circuit is: P = (U I) x power factor
So, you need to know the power factor of the load in order to calculate the power. With the information you supply, you can only calculate the apparent power, expressed in volt amperes, which is the product of the supply voltage and the load current -using the figures that you supply, this will be 24 V.A.
If the 100 amps is powered by 10 volts, you have 1 kw, or 1000 watts. watts = volts X current The 'k' simply means kilo, or thousand.
Wattage is unit of power which is the product of Voltage in V and Current in Amps. If you know the current drawn by the appliance with 1200 Watts then you can calculate the Voltage = Power/ Current. For eg. if the current drawn by the appliance is 100A then the voltage is 1200/100 i.e. 12 Volts.
The question is invalid. Volts is a unit of electrical potential in fundamental units of joules per coulomb. Watts is a unit of (electrical) power in fundamental units of joules per second. As such, you can not determine volts from watts without knowing something else, such as amperes (coulombs per second) or ohms. The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts. For example 1 amp * 110 volts = 110 watts You have two unknowns for this equation, 1) the voltage which you want to find, and 2) the amperage. You must know the amperage to find your answer. In household current the voltage is 110-120. However, if you use a car battery, the voltage is 12. You could have the amperage and then use the equation above. 4 amps: 500watts = 4amps X ? volts. 500 watts/4amps = 125volts (close to household current) 42 amps: 500watts = 42amps X ?? volts. 500watts/42amps = 11.9volts prox. (close to a car battery) 1 amp: 500watts = 1amp X ??? volts. 500watts/1amp = 500volts (about like a large electric eel--300 to 800 volts)
In U.S. voltage is usually referred to as 120 nowadays. so if in U.S. substitute 120 where 115 appears below. Power = Amperage times voltage So, in your example, 8.5 times 115 = Watts
The electrical code states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. Therefore you can have a load of 1,920 watts on this circuit. Assuming you install 8 watt bulbs you can have 240 on this circuit.
100 watts
This will still only produce 12 volts. It will produce 1200 watts. watts is the result of Volts times Amps.
Watts are amps x volts, so w/o the volts the question can't be answered. At 100 volts it'd be 15 amps.
A three wire home distribution service rated at 100 amps has a wattage capacity of;From L1 to L2 at 240 volts x 100 amps = 24000 watts or 24 kilowatts. From L1 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts. From L2 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts.
As asked, the question cannot be answered. At 1 volt, 300 Watts = 300 Amps. At 10 volts, 300 Watts = 30 Amps. At 100 volts, 300 Watts = 3 Amps. At 120 volts, 300 Watts = 2.5 Amps. At 240 volts, 300 Watts = 1.25 Amps. To calculate the relationship between Amps, Volts and Watts, use the formula: Watts = Amps * volts
Watts = Amps * Volts Watts = 20 amps * 100 Volts Watts = 2000 2,000 Watts or 2k Watts
Watts = Amps * Volts Watts = 20 amps * 100 Volts Watts = 2000 2,000 Watts or 2k Watts
If the 100 amps is powered by 10 volts, you have 1 kw, or 1000 watts. watts = volts X current The 'k' simply means kilo, or thousand.
When you multiply amps x volts the product is watts. Using this formula W = Amps x Volts should give you your answer.
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). HOWEVER, if you have at least least two of the following three: amps, volts and watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship between them.
The answer is "It Depends" Watts of electircal power is defined as Voltage x Current. Amperage is a unit of current. In most houses in the US the voltage is 120 volts AC. A 100 watt light bulb in the house would have 120 volts across it so the current flowing would be: Watts = Volts x Amps 100 watts = 120 volts x I amps A amps = 100 watts / 120 volts A amps = 5/6 amps ANSWER watts is a product of voltage and current .One quantity will never suffice
