Given below are two statements:
Statement I: If the number of turns in the coil of a moving coil galvanometer is doubled then the current sensitivity becomes double.
Statement II: Increasing current sensitivity of a moving coil galvanometer by only increasing the number of turns in the coil will also increase its voltage sensitivity in the same ratio In the light of the above statements, choose the correct answer from the options given below:
Show answer and solution
Answer: (a)
- Current sensitivity , so doubling doubles it: Statement I is true.
- Voltage sensitivity ; doubling also doubles the wire length, so doubles and voltage sensitivity stays the same: Statement II is false.
- So the answer is (a).
