A) 60 V and 80 A
B) 120 V and 160 A
C) 60V and 40 A
D) 120V and 40 A
Correct Answer: A
Solution :
\[V={{V}_{0}}\left( 1-\frac{I}{{{I}_{s}}} \right)\] \[V=60\,\,V,\]\[{{I}_{3}}=160\,A\] \[V=60\left( 1-\frac{I}{600} \right)\] \[I\propto t\,\,and\,\,{{V}_{0}}\propto \frac{1}{t}\] For 5 mm, \[l=\frac{5}{10}\times 160=80\,A\] And \[{{V}_{0}}=120\,V\] \[{{V}_{0}}=120\left( 1-\frac{80}{160} \right)=60\,V\]
