Current Electricity Charging Discharging Of Capacitors Question 211
Question: In an experiment of meter bridge, a null point is obtained at the centre of the bridge wire. When a resistance of 10 ohm is connected in one gap, the value of resistance in other gap is
[MP PET 1994]
Options:
A) $ 10,\Omega $
B) $ 5,\Omega $
C) $ \frac{1}{5}\Omega $
D) $ 500,\Omega $
Show Answer
Answer:
Correct Answer: A
Solution:
Wheatstone bridge is balanced,
Therefore $ \frac{P}{Q}=\frac{R}{S} $ or $ 1=\frac{10}{S} $
Therefore $ S=10,ohm $
