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 $500 \mathrm{~V}$ and produce currents of $80 \mathrm{~mA}$ (or even larger). A typical pulse lasts for $10 \mathrm{~ms}$. What power and how much energy are delivered to the unfortunate enemy with a single pulse, assuming a steady current?

Step 1
Given: Voltage (V) = 500 V Current (I) = 80 mA = 0.08 A Using the formula for power: \[ P = I \times V \] \[ P = 0.08 \, \text{A} \times 500 \, \text{V} \] \[ P = 40 \, \text{W} \] Show more…

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 $502 \mathrm{~V}$ and produce currents of $79 \mathrm{~mA}$ (or even larger). A typical pulse lasts for $10 \mathrm{~ms}$. What power and how much energy are delivered to the unfortunate enemy with a single pulse, assuming a steady current?
Electric eels. Electric eels and electric fish generate large potential differences that are used to stun 9 enemies and prey. These potentials are produced by cells that each can generate 0.10 V. We can plausibly model such cells as charged capacitors. (a) How should these cells be connected $(\mathrm{in}$ series or in parallel) to produce a total potential of more than 0.10 $\mathrm{V} ?$ (b) Using the connection in part (a), how many cells must be connected together to produce the 500 $\mathrm{V}$ surge of the electric eel?
