60 or 120

[domnic]

When you get shocked by 120 volt ac is it 60 or 120 times per second ?

I would say just once, by AC.
But if you consider that the direction of the current flow does not matter, you could say you are being exposed to 120 pulses of current per second.
Try putting a diode in series and tell me if it feels any different. Then try a full wave bridge...:angel:

Hopefully, you learn the lesson the first time!:slaphead:

You have 120V RMS being applied to you. It is similar effective voltage to a resistive load as 120V DC.

Actual peak of each cycle reaches about 170 volts, but there is two peaks every cycle - each is opposing polarity of the other and half a cycle apart

The Last Time I was Hit ,,,,Was my own Fault ,,, You get lazy in old Age ....

Clearing all Circuits through a Area in a Hospital about the size of 3 gymasiums ...xfmrs in air down to all circuits passing through area .

All fire alam , all critical life ...

No I did not Kill any one ....But the old man on the job got that part of it , they needed it done and safely ..

We were putting in 8 new MRI's and Several New Cat Scans and X-Ray Machines ... Miami 2007 .


I got Hit Off of a bare tape spot on my Cutters .... My fault , getting old ,,,, 4 extension boxes with live wires in them , what a mess , Roof Units were still Running .... That is what got me .... But by habit of years ... I always work so if HIT , it will only go through the hand , not the Body ...

CABESHE ...






When you Feel like a Bell and its Ringing ....

And your Sense gets smaller and its Singing ...

You are being " Hit "

I think I know what you are asking. If I am correct, the answer you are looking for would be 120 times per second. That's because there would be two voltage peaks per cycle with one 0 line crossing keeping the 'shocks' apart.

Yes, but those peaks are also around 170 volts. The 120 volts RMS has similar current and power effects as being connected to 120 volts DC.

Yes, I know that.

IPP voltage is a moot point. The question was about frequency. What it boiled down to was how many shocks does a person get per cycle, one or two?

I would say two. One for each peak if the body was at the 0 volt reference.

You are right, so was I. I guess OP really needs to clarify exactly what it is he wants to know.

Not that I plan to try it, but a 120 V RMS shock should feel about the same as a 120 volt DC shock, I think.

AC shocks and DC shocks are different. I know that by experience.

I can feel the 'vibration' of the shocks at 60 Hz. There is no 'vibration' with DC. It's a solid, relentless hit. No zero crossing so the 'let go' ability is very hampered with DC at the same voltage as AC. So a 120 volt DC shock is far more dangerous and hurts more than a 120 volt 60 Hz AC shock.

The RMS of AC is actually a 'heating equivalent' that takes place over many cycles and then averaged out.
