are you on facebook?

ok on cross trainer i do 600 cals in 30 mins-can you tell me how many watts i would be using overall? i have problems logging in here sometimes are you on facebook?

what i would like to know in understanding voltage and current is-if someone was subjected to 2 electric shocks say from hand to forearm one with a current limited to 10ma, the other unlimited. if the voltage was 1000 v ac and the same conditions, the resistance of the skin being so that 1000...

'Possible heart fibrillation 500 MA Dc after 3 seconds' Also in this example in 'All about circuits' the writer says that with dry skin the resistance across his body is about 1 meg ohm. So let's say that to carry half an amp across this the equation would be V=IR. =0.5x1000,000. So that sounds...

Perhaps I am thinking about those taser guns and cattle prods. Trying to determine which hurts the most in a constant dc voltage. I do realize these devices use electronics to pulse or oscillate. Putting it a different way, assuming for some reason the shock is not fatal and went say just...

Ok yes that is also true so not getting to my point. a relatively small amount of current is needed from an ac shock due to sending the heart out of sync so to speak. I think it is a large charge of dc they use to take it out of fibrillation. If we stick to dc then and consider death by heating...

stewartcs, Yes I should have realized about the full voltage not being felt just as across a light bulb or heater due to different amounts of resistance. Short of connecting a volt meter in between would the resistance of the circuit(through the person being shocked) need to be known? Also I...

Understanding the amount of 'power' in Watts to kill a human. It is said that around 20ma is enough to kill. So I would have thought it does not matter about the voltage as long as 20ma is passing through the heart. obviously it would require different voltages depending of the resistance...

you have all overlooked something. generating power for a bike to put out 500 w. at the wheels would take a lot more overall energy. heat lost through body, body's usual working load? i recon someone generating 500 w is actually consuming about 2k. give or take a few watts. that got you thinkin...
