Question
Internal resistance of battery is 5ΩTwo identical fuses are rated at 10A. If they are joined
Options
A.In parallel, the combination acts as a fuse of rating 20 A
B.In parallel, the combination acts as a fuse of rating 5 A
C.In series, the combination acts as a fuse of rating 10 A
D.In series, the combination acts as a fuse of rating 20 A
Solution
In parallel combination current gets divided therefore parallel combination supports i = i1 + i2 is 20A in series current remain same therefore the series combination supports i = 10A.
