In a meter bridge experiment, with a standard resistance in the right gap and a resistance coil dipped in water (in a beaker) in the left gap, the balancing length obtained is $l$. If the temperature of the water is increased, the new balancing length

• A

  $<l$
• Correct answer
  B

  $>l$
• C

  $=0$
• D

  $=l$

Hence, the correct answer is option: 'B'.
