Scroll down to related links and look at "Electrical voltage V, amperage I, resistivity R, impedance Z, wattage P".
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
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.
Generators are rated in watts because watts are the scale on which energy is measured.
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.
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.
Watts is a measure of power, while amps is a measure of electric current. The relationship between watts and amps depends on the voltage of the circuit. The formula to calculate power (in watts) is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps.
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.
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

voltage depend on current and resistance r.p.m depend on no of pole
voltage and frequency both are different quantity.. don't mix it...
The relationship between wavelength and peak voltage depends on the type of wave. In electromagnetic waves like light or radio waves, there is no direct correlation between wavelength and peak voltage. However, in signals like electrical voltage waveforms, the peak voltage is often correlated with the frequency of the wave.
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.
Have to know the voltage to answer this question.
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.
The formula you are looking for is I = W/E.
