The diagram above illustrates a meter bridge circuit underbalanced conditions. Determine the value of x.
50.cm
10.0 cm
28.6 cm
57.2 cm
Correct answer is A
Using wheatstone bridge principle;
\(\frac{2}{x} = \frac{2}{(100 - x)}\)
2(100 - x) = 2 x \(x\)
200 = 2\(x + 2x\)
200 = 4x
x = \(\frac{200}{4}\)
= 50cm
