60 hz is how many volts?
438964
North American 120 volt electricity is generated at 60 Hz Alternating Current (AC). Most foreign 220–240 volt electricity is generated at 50 Hz Alternating Current (AC).

The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor. ... Therefore, for a 60-Hz system, the formula would be: 60 x 60 x 2 = 7,200 no-load rpm Ã· number of poles.

The hot wire is not always positive, but flips between positive and negative. Usually the frequency is 60hz and one cycle includes a state of positive, and a state of negative, meaning it flips 120 times per second.

The information on the label tells us that the microwave oven needs 120 volts of electricity in the form of alternating current (AC) to operate, and draws 5 amps (amperes) of current during its use. The 60 HZ number means that the current alternates at a rate of 60 times per second.

You point out in your letter that some consensus standards consider live parts operating between 50 and 60 volts, DC, to be non-hazardous under certain circumstances. However, OSHA considers all voltages of 50 volts or above to be hazardous.

Generac states that generators less than and equal to 600 volts are medium-voltage and generators greater than 600 volts are considered high voltage. Generators producing 4160 volts are common in many industries for large motors that require high voltage.

20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts. 25-amp 120-volt circuit: 25 amps x 120 volts = 3,000 watts. 20-amp 240-volt circuit: 20 amps x 240 volts = 4,800 watts.

Harmonics are voltages or currents that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency. So given a 50Hz fundamental waveform, this means a 2nd harmonic frequency would be 100Hz (2 x 50Hz), a 3rd harmonic would be 150Hz (3 x 50Hz), a 5th at 250Hz, a 7th at 350Hz and so on.

Voltage is pressure or a force that can drive a flow of electrons given the chance. ... Hertz is a measure of frequency. It is used in AC to show the rate of change. It was measured in Cycles per second but now is in Hertz but they are both the same.

Cycles: 50 Hz vs. North American 120 volt electricity is generated at 60 Hz Alternating Current (AC). Most foreign 220–240 volt electricity is generated at 50 Hz Alternating Current (AC).

the peak to peak voltage = 6 squares from the highest point to the lowest and each square is worth 10V. So the peak to peak voltage = 60 V. the peak voltage ( Vo )= half the peak to peak voltage = 60 / 2 = 30 V.

The voltage in India is 220 volts, alternating at 50 cycles (Hertz) per second. This is the same as, or similar to, most countries in the world including Australia, Europe and the UK. However, it's different to the 110-120 volt electricity with 60 cycles per second that's used in the United States for small appliances.

We should be aware that why use 50Hz or 60Hz, rather than lower or higher frequency. ... The frequency of alternating current is 50(60) Hz, the current direction changes 50(60) cycles, 100(120) times per second. The electric motor is made according to the basic principle of the rotating coil in the magnetic field.

In Mexico the standard voltage is 127 V and the frequency is 60 Hz. You can use your electric appliances in Mexico, because the standard voltage (127 V) is (more or less) the same as in Canada (120 V).

Convert Revolutions Per Minute to Hertz 1 Revolution per minute is equal to 1/60 Hertz. RPM is commonly used to measure engine performance. Period is the inverse of frequency. 1 RPM = 1/60 Hz or approximately 0.0166666666666667 Hz.

Although 50Hz transformers require more copper and iron, 60Hz transformers require more expensive plates to prevent eddy current losses. The voltage and frequency of AC electricity varies from country to country throughout the world. ... He had calculated that 60 cycles per second or 60Hz was the most effective frequency.
