Correct answer: A. 1.5 ~A

In each row all the 5000 electroplaques are connected in series. Therefore, equivalent emf

=0.15 \times 5000=750 \mathrm{~V}

. Equivalent resistance

=0.25 \times 5000=1250 \Omega

. All 100 rows are connected in parallel. Therefore voltage

=750 \mathrm{~V}

. Equivalent resistance

=\frac{1250}{100}=12.50 \Omega

. Thus resultant circuit of eel becomes Eels are able to generate current with biological cells called electroplaques. The electroplaques in an eel are

Eels are able to generate current with biological cells called electroplaques. The electroplaques in an eel are

Current across

500 \Omega=\frac{V}{R}=\frac{750}{500+12.50}=1.46 \mathrm{~A}

I \approx 1.5 \mathrm{~A}
