Textbook Problem

For the network in Figure P18.60, show that the resistance between points a and b is R a b = 27 17 Ω . (Hint: Connect a battery with emf ε across points a and b and determine ε/I, where I is the current in the battery.)Figure P18.60

(a)

To determine
The maximum electric power that the electric eel can generate.

Explanation

Given Info:

The total number of cells is 4.0Ã—103 .

The potential difference of the each electrocyte is 150.0â€‰mV .

Explanation:

Formula to calculate the terminal potential difference is,

Î”V=N(Î”Ve)

• Î”Ve is the potential difference of each electrocyte
• N is the total number of cells

Substitute 4.0Ã—103 for N and 150.0â€‰mV for Î”Ve to find the total terminal potential difference,

Î”V=(4.0Ã—103)(150.0Ã—10âˆ’3â€‰V)=6.0Ã—102â€‰V

Thus, the total terminal potential difference of cells is 6.0Ã—102â€‰V

(b)

To determine
The energy released in one shock.

(c)

To determine
The height of a 1.0kg mass to be lifted so that its gravitational potential energy equals the energy released in 3.0×102 such shocks
