What else can I help you with?
Which would be the stronger electrical shock between 330V 106 mA and 1000V 33 mA?
There's an old saying: "It's the volts that jolts, but the mils that kills" To which you could add, "it's the power that fries you"
How many joules are in the newpoint surge protector 330V E87630?
The number of joules in a surge protector is a measure of its energy absorption capacity, not its voltage rating. In order to determine the joules rating of the Newpoint Surge Protector model E87630, you would need to refer to the product specifications or documentation provided by the manufacturer.
Convert ac voltage rms to dc voltage?
The dc voltage of a rectified ac voltage will be the peak value of the ac voltage less the forward voltage drop of the diode.The rms voltage of a sinusoidal ac voltage is sqrt(peak) / 2, but you also have to consider if the ac voltage is balanced around zero.For a normal US house voltage of 117VAC, the peak voltage is about 165V, or 330V peak to peak. Your dc voltage is then around 164V.Run that rectified voltage through a capacitor, and you will still have 164V peak value, but the voltage over time will dip because the capacitor will discharge during diode off time, and recharge when it turns back on.AnswerA given value of a.c. rms voltage is exactly equivalent to the corresponding value of d.c. voltage. For example, 120 V (rms) is exactly equivalent to 120 V d.c. This is why the alternative name for 'rms voltage' is 'effective voltage'. This is based on the fact that a current of, say, 10 A (rms) will do exactly the same amount of work as a d.c. current of 10 A. And, of course, voltage and current are proportional.
Do you need two jumpers from your outdoor condensor compressor to the start capacitor if you only have one and does it need 220 or 120 if it is a 40mfd rated for 330v?
Do you have a dual capacitor that starts both the compressor and the fan motor? You need 230V to power the compressor. You should have one wire from the capacitor going from the start terminal on the compressor and one going from the common terminal to common on the capacitor.
What is the RMS values of AC Current and Voltage?
RMS stands for Root Mean Square. Basically it's what your AC voltmeter measures. So if you have a 120 volt AC signal, what you are saying is that the measured RMS voltage of the signal is 120 volts.The RMS voltage is a measure of the equivalent heat of a DC voltage. So a 120 volts RMS AC signal, which varies between +168 volts and -168 volts and back 60 times every second, has the same heating power that a DC voltage of 120 VDC would have.RMS voltage divided by 0.707 equals peak to peak voltage.Alternative AnswerThink of two types of electric saw: a circular saw and a reciprocating saw. We measure the speed of these two saws in two different ways, revolutions per second and strokes per second. Is there any way of comparing the two? Well, yes, we could describe both in terms of the length of cut they would make in the same period of time (their cutting speeds).Following this analogy, we compare direct current and alternating current by determining the heating effect of both currents. For example, if a direct current of, say, 10 A, produces a heating effect of x joules, what value of alternating current would produce exactly the same heating effect? Well, an experiment would show that this would be 0.707 times the amplitude (peak value) of that AC current which, in this particular example, would be a little over 14 A. So, instead of specifying the current's peak value, we always specify its rms-value.Since voltage and current are proportional to each other, we can measure voltage in the same way -i.e. Vrms = 0.707 Vmax. So, as the first answer explains, a nominal voltage of 120 V actually peaks at 168 V.(You may ask, why not simply use an average, rather than rms value? Well, apart from the fact you wouldn't be able to compare it to DC, the average of a complete positive/negative cycle would be zero!)
