@Bhanu Nepal I just measured my skin resistance, dry skin is around 14 MΩ while wet skin is around 3M. So if I am parallel to that 120v circuit there is no way the electrons will chose my body as a path, hence no current flowing through my body so I will not be electrocuted. but if I wan in series there my body is the only path to ground and my skin's resistance will breakdown and I'll die from that voltage.

If you are in parallel with 120V, then you will be connected to 120V and you will 100% die. Clearly you are not an electrician and you have NEVER touched 120V. I don't suggest you 'test' your theory...

I am an Electrical Engineer and I know exactly what I am talking about. If you're in parallel with an already existing circuit with and already existing load, i.e. you touch an exposed live and neutral wires that are perfectly connected to the load , the current will not flow through your body because your body is offering a very high resistive path. but if you're in series with that load then yes you will definitely die. to make is easier for you to understand try drawing a circuit with 2 resistance in parallel, the first resistance is 1uΩ and the second resistance is 15MΩ resistance.

@@aqeelalmousawi1500 The humand body is not 15M ohms. You will get killed if you attempted to connect yourself in parallel with another load where both are connected to 120V, not matter the resistance of the load. Resistors in a 120V parallel circuit will both be supplied by 120V. This converstation is closed. Just be sure you don't test your 'theory.'

Sir pleaae tell I recieved electric shock today when starting the motor.it pushes me little.after got shock I didn't feel any health hazards.but feeling anxiety I am safe or not please comment me sir. It didn't holdme.it push my finger in fraction of second.please reply

I'm sure you understand I'm not a medical professional, so I can't give you any advice. Me and probably all electricians have been shocked many times as you described. I and those I know have not had any medical issues because of such a shock.

So it seems if you are being shocked just -above- the let-go threshold and can't seem to let go, AND this is AC CURRENT, then the best thing to do would be to -fall- so that when the AC is at and near the low-current levels (as it passes through zero), the muscles of the hand would LET-GO or BREAK-FREE due to gravity. More exact details, given your numbers from the studies, could be made. THIS COULD SAVE LIVES!!

If this happens you can 'can' fall, then it happens automatically. This is not something someone can do on their own. Example, you are leaning on a metal object and you get shocked. I was 'hung up' on 277V and I fell, so I'm still alive, but it happend because I 'could' fall.

Why will gloves protect me from a 120v shock (indoors) but wearing rubber soled shoes will not?

If you are insulated, then you are insulated. If you are getting shocked, then you are not insulated.

Thanks, maybe feet and floor form a capacitor with shoe soles being the dielectric. I can hold a shoe in my hand and touch 120v with no shock. If I spot a lineman with a Megger ohm meter I'll have my shoe sole checked, but I suspect the resistance will be too high for a shock. When 1000 ohms is stated for resistance of human body hand to foot the resistance of shoes and house component are never mentioned. I guess it's never been studied, if I still had access to lab equipment it might be worth a study.
