Question

The balance length on wire AB if resistance of wire AB is 991W, is:

• A. 9.91 m
• B. 0.09 m
• C. 1 m
• D. Balance point will not be obtained

Answer 1

Answer: (C)

1 m

Answer 2

V_CD = f × Balance length

9.91 V = × B.l

9.91 V = $\frac { 100 } { 10 }$ × $\frac { 991 } { 1000 }$ × B.l

B.l = $\frac { 9.91 } { 9.91 }$= 1 m
