When a known standard resistor of 2(Omega) is connected to the 0.0cm end of a meter bridge, the balance point is found to be at 55.0cm. What is the value of the unknown resistor?
-
A.
1.10(Omega) -
B.
1.64(Omega) -
C.
2.44(Omega) -
D.
27.50(Omega)
Correct Answer: Option B
Explanation
(frac{R_1}{R_2}) = (frac{L_1}{R_2})
(frac{2}{R_2}) = (frac{55}{45})
R = 1.64(Omega)
