Textbook Problem

An electric eel generates electric currents through its highly specialized Hunter’s 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?

(a)

To determine

To compare: The brightness, current and power delivered in each bulb in case 1.

Explanation

Given Info:

Explanation:

The circuit in case1,

Since, the bulbs A and B are in serial connection with the battery and the resistance of both the bulbs is same; the current through both the bulbs are the same with respective of Ohm’s Law.

Formula to calculate the power is,

P=I2R

  • I

(b)

To determine
The brightness, current and power delivered in each bulbs.

(c)

To determine
Which case bulbs are having more brightness.

(d)

To determine
Whether the second bulb go out if the other one fails. If it is not going out, will the brightness be the same or more.
