Giant electric eels can deliver a voltage shock of 5.00×102 V and up to 1.00 A of current for a brief time. What is the maximum power a giant electric eel can deliver to its prey during this time? maximum power:   W The body of a snorkeler swimming in salt water has a resistance of about 605 Ω. If the snorkeler is unfortunate enough to be struck by the eel, what current will flow through her body? current:     A A current of about 500 mA can cause heart fibrillation and death if it lasts too long. Is the current through the swimmer in this case large enough to be dangerous? yes no What power does the snorkeler receive from the eel? power:

In Europe the standard voltage in homes is 220 V instead of the 120 V used in the United States. Therefore a "100 W" European bulb would be intended for use with a 220 V potential difference.

A heart defibrillator being used on a patient has an RC time constant of 11 ms due to the resistance of the patient's body and the capacitance of the defibrillator. If the defibrillator has an 8.5 μF capacitance, what is the resistance of the path through the patient in kΩ? (You may neglect the capacitance of the patient's body and the resistance of the defibrillator.) If the initial voltage is 12.5 kV, how long does it take to decline to 6.00 × 102 V in ms?
