Question

two identical fuses are rated at 10 A , if they are joined

• 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

Answer 1

Answer: (A), (C)

The correct options are
A in parallel, the combination acts as a fuse of rating 20 A
C in series , the combination acts as a fuse of rating 10 A

If two identical fuse are connected in parallel than combination current will be addition of both the current

$I=10+10=20A$

If two identical fuse are connected in Series than combination current will be same in both fuse

$I=10A$

Hence, Option (A) and option (c) both are correct.
