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


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


Given Info:

The total number of cells is 4.0×103 .

The potential difference of the each electrocyte is 150.0mV .


Formula to calculate the terminal potential difference is,


  • ΔVe is the potential difference of each electrocyte
  • N is the total number of cells

Substitute 4.0×103 for N and 150.0mV for ΔVe to find the total terminal potential difference,


Thus, the total terminal potential difference of cells is 6.0×102V


To determine
The energy released in one shock.


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
