The human body has an average resistance of about 300 ohms and cannot reasonably be considered a conductor; therefore, electromagnetic induction is not possible. The body is truly the load in the circuit described.

Electrocuting oneself

Yes. Increased resistance will decrease the current which forces reduced voltage.
You make people miserable and there's nothing they can do about it, just like god.

Increased resistance will decrease the current which forces reduced voltage. Assume you hook up a measurement device that ideally draws no current, once to the body and once to the wire. What will I measure?

Uh.....
Why the fuck is this in mathematics?

What will I measure?It depends on the voltage applied. E=IR Assuming 30,000 volts and Cato's 300 Ohms 30,000/300=100 amps. However, if this is to lead back to the induction question, the resistance would keep any respectable voltage from developing in the first place and there would be minimal current if any.

But the issue is still, there will be a voltage induced along your body, and I am pretty certain that it will be the same as in a wire. No harm done. I had a suspicion you had at least a smattering of electrical training and from your posts I had a sneaking suspicion a whole lot of physics was there also but I was not aware of that, I haven't been around long enough on this forum to know for sure. By your last post I was also beginning to wonder if you were baiting me or teasing me. There comes a point when one must bow to ones lack of knowledge and back off. On the other hand your "teasing" had a good effect on me, I sweated a little but it forced me to do some serious thinking. So hope to trade posts with you in the future. Happy Thanksgiving (if you and yours observe Holidays (some diehards on this forum are so anti-religious they refuse to celebrete any holiday that even slightly smacks of religion [of course you are probably more aware of that than I am;])

The body is truly the load in the circuit described. Of course not. Having reread my post I see the potential confusion in my reply. I used 'and' to invoke an additional condition, not as 'therefore' where the validity of the latter statement was dependent on the former. The material affected when considering electromagnetic induction is assumed to be a conductor, a general classification of materials (e.g. metals) that have the requisite molecular structure to support the concept of 'free' electrons dictated primarily by valence orbital sharing of electrons. For example, your not going to be very successful inducing a voltage in pure water.  |
