How do you covert watts to amps?
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
A 100 amp 3 phase power supply is good for how many total amps?
100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V x 1.73 = 83040 watts. - 3 single phase 480v (L-L voltage) heaters, 100amp. 173A x 480V = 83040 watts. - 3 single phase 277v (L-N voltage) heaters, 100amp. 300A x 277V = 83100 watts.
Why are generators rated in watts?
Generators are rated in watts because watts are the scale on which energy is measured.
Assume a device draws 50ma of current and 150vdc across it what is its resistance?
Ohm's law: Voltage = Current times Resistance Solve: Resistance = Voltage divided by Current So, a device drawing 50ma with 150V has a resistance of 150 / 0.05, or 3000 ohms. p.s. Since power is volts times amps, that device is dissipating 7.5 watts.
What is 232 in RS232 and MAX232?
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
What is relation between wavelength and peak voltage?
There is really no relation.
What is the relation between amperage and capacitance?
The relation between amperage and capacitance is that amperage is equals to capacitance times the rate of voltage change over time. This voltage refers to instantaneous voltage.
What is relation between voltage and conductors?
Your question is unclear. But, if you are asking what the relationship between voltage and the distance between conductors is, then the higher the voltage, the greater the distance must be.
Calulate kw FROM single-phase voltage and ampere?
Watts = Voltage X Amperes X Power Factor Power Factor = Cosine of the Angle between Voltage and Current For purely resistive circuits, Power in Watts = Voltage X Amperes Watts divided by 1000 = kiloWatts
What is the relation between the depletion region and barrier voltage?
0.7
Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole
What is relation between frequency and voltage of that frequency?
voltage and frequency both are different quantity.. don't mix it...
How many watts required to get 230 volts from generator?
There are no watts to generate volts!! There is a relation that is watts = volts * Amps Generators are set up to generate a specific voltage regardless or watts or amps capacity it has.
How many watts is 7 amps?
In general, multiply the (rms) current by the (rms) voltage to get the power. If the voltage to the appliance is 120 Volts, then the power of 4.2 Amps is 504 Watts. If the voltage is 240 Volts, then 1008 Watts. Note: To be technically accurate, you must also multiply the cosine of the phase-angle between current and voltage. For any typical appliance, this is 1 and can be ignored. <<>> There are zero watts in 4.2 amps. Watts = Amps x Volts. Without a voltage stated the wattage can not be calculated.
What is relation between rms voltage and peak to peak?
Vrms=1.414xVpk to pk
How many watts is 5 amps?
600 This depends on the voltage Voltage x Amps = Watts ex. At 120 volts 5 amps WILL BE 600 watts But at 110 Volts (Some house voltage), it will be 550 watts And at 277 Volt (commercial-Industrial Voltage), it would be 1385 Watts If you know Watts (Like a 75w Incandescent Lamp) and the Voltage: Watts / Volts = Amps So 75w / 120v = 0.625a The last would be Watts / Amps = Volts 600w / 5a = 120v
How many amps are in 1500 watts?
Those units describe different types of quantities, and the question is something likeasking "How many hours are in 15 gallons ?".When an electric current is consuming or dissipating 1,500 watts of power as it flowsfrom one point to another, then the number of amps of current is(1,500) divided by (the voltage between the two points) .
