A defibrillator generates a voltage of about 500 V. If the resistance of skin is about 1
million ohms, how much current does the defibrillator generate in the body? Hint: V =
I * R - correct answer-0.0005 A
A defibrillator is a device which: - correct answer-Creates a high voltage across the
heart
A person is not generally worried about using a 5 Amp electric grill, even though 1
Amp of current across the heart is enough to stop it from beating. Why is that? -
correct answer-The skin is able to protect the heart by resisting a low current.
Electrical current is: - correct answer-The movement of electrical charges through
the body
Electrical current through muscles can cause them to: - correct answer-Contract
Electrolytes are: - correct answer-Molecules which carry electrical charge
If the current in the bloodstream is 0.0001 Amps and the heart creates about 0.06 V
of voltage, then how much resistance does the bloodstream cause to the flow of
electricity? Hint: V = I * R - correct answer-600 Ohms
It is safe to use electricity to send a current through muscle or brain tissue. - correct
answer-True
