Magnetic effects involving Jupiter’s moon Io result in an effective voltage of about 400 kV, which drives current of some 5 MA between Io and Jupiter’s polar regions. At Jupiter the current produces auroras analogous to those on Earth, as well as powerful bursts of radio waves that help radio astronomers analyze the Jovian current system. Estimate the total power associated with this current system, and compare with the 2-TW rate at which humankind consumes electrical energy.

- An electric eel generates electric currents through its highly specialized Hunters organ, in which thousands of disk-shaped cells called electrocytes are lined up in series, very much in the same way batteries are lined up inside a flashlight. When activated, each electrocyte can maintain a potential difference of about 150 mV at a current of 1.0 A for about 2.0 ms. Suppose a grown electric eel has 4.0 103 electrocytes and can deliver up to 3.00 102 shocks in rapid series over about 1.0 s. (a) What maximum electrical power can an electric eel generate? (b) Approximately how much energy does it release in one shock? (c) How high would a mass of 1.0 kg have to be lifted so that its gravitational potential energy equals the energy released in 3.00 102 such shocks?arrow_forwardThe 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.

- Electric Eels. Electric eels generate electric pulses along their skin that can be used to stun an enemy when they come into contact with it. Tests have shown that these pulses can be up to 500 V and produce currents of 80 mA (or even larger). A typical pulse lasts for 10 ms. What power and how much energy are delivered to the unfortunate enemy with a single pulse, assuming a steady current?arrow_forwardThe generator at a large power plant has an output of 2,000,000 kW at 23,000 V.

- Household electrical outlets operate at 120 Volts. A microwave oven is rated at "120V, 1.0 kW" meaning that if you plug the oven into an electrical outlet, the appliance will consume 1.0 × 10³ Joules of electrical energy per second. How much current does a microwave oven draw when it is plugged in and turned on?

The surface area of one plate is 1778 m2. With the switch open, the plates are uncharged, and separated by a distance d = 5 mm. When the switch is closed, the distance between the plates decreases Im by a factor of half. What is the spring constant, in Newton/meter, for each spring?
