Peak voltage of the 480 volts and the DC bus voltage of a drive (supplied with 480 volts anyway) are going to be about the same value of about 680 volts. The AC voltage scenario will reach zero volts 120 times in one second if frequency is 60 Hz. RMS voltage of 480 is supposed to mean the effective voltage is approximately equal to 480 volts DC.
33. I have been looking around for an easy way to convert 12V to 5V. I have seen some people saying that a simple resistor is all that is needed. Volts = Ohms ⋅ Amps V o l t s = O h m s ⋅ A m p s. Amps = Volts Ohms A m p s = V o l t s O h m s. Ohms = Volts Amps O h m s = V o l t s A m p s. So applying a resistor will diminish the voltage of
The DC offset of the waveform, V 0 V_0 V 0 . The waveform shape and characteristic voltage determines the RMS voltage formula we need to use. We've collected some common waveforms and their RMS value formulas in the handy table below. These RMS voltage equations do not take DC offsets into account yet — read on to learn how we deal with those!
What you mean: the battery voltage has dropped 60 mV. If the lightbulb was designed to work on 2.4 V, why would the manufacturer list "(AC 100-240V, 60 Hz)" on the bulb? Being able to use it on 2.4 V DC would be a nice feature. The circuit in the lightbulb need a high voltage of at least 100 V AC. It has to do with how the circuit is deigned.
Make sure the selector switch on the power supply is set for your country's voltage, either 120 or 240VAC. 4. Plug in your portable power supply using a standard computer cable for the AC receptacle. 5. Plug in the battery adapter into the DC receptacle. 6. Turn on the power supply with the switch located on the IEC C14 electrical receptacle 7
