Q5 / 16 · NTA Abhyas (NEET) 2020 · Physics · Experimental Physics

The deflection in a moving coil galvanometer is

  • A
    directly proportional to the torsional constant
  • Correct answer
    B
    directly proportional to the number of turns in the coil
  • C
    inversely proportional to the area of the coil
  • D
    inversely proportional to the current flowing

Solution

Deflection is directly proportional to electric current in moving coil galvanometer.

i=knBAθ⇒θ=nBAki⇒  θ∝n

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