Rating of 12 V battery is 80 A, this means that if we join any conducting wire between two terminals of battery, we get 80 A electric current and internal resistance of battery = `Omega`.

Options

A. 0
B. 0.015
C. 0.15
D. none of these

Answer

C

Explanation

0.15
R = `(V)/(I) = (12)/(80) = 0.15 Omega`
