Question
The human body can exhibit a wide range of resistances to current depending on the path of the current, contact area, and sweatiness of the skin. Suppose the resistance across the chest from the left hand to the right hand is 2.00 x 106 (a) How much voltage is required to cause possible heart fibrillation in a man, which corresponds to 430 mA of direct current? 9.4e5 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. V (b) Why should rubber-soled shoes and rubber gloves be worn when working around elecricity? Because the resistance is much higher, it can withstand more shock Score: 4.55 out of 4.55 Comment Need Help? Talk to a TutorExplanation / Answer
a)V= IR
V= 0.43x2x106
V= 8.6x105 volt
b) Wearing rubber shoes and gloves will increase the resistance to a very higher value and so currrent will be very low to cause a shock
