The internal resistance of a cell of e.m.f. 12V is $5 \times 10^{-2} \Omega$ . It is connected across an unknown resistance. Voltage across the cell, when a current of 60 A is drawn from it, is
Text Solution
Verified by ExpertsThe correct answer is:
C
$V = E = ir$ = $12 - 60 \times 5 \times 10^{-2}$ = 9V.
