Which of the following is used in magnetic wind instruments to determine the amount of oxygen?
A. Change in resistance
B. Change in capacitance
C. Change in inductance
D. Change in concentration
Answer:A
Which of the following is used in magnetic wind instruments to determine the amount of oxygen?
A. Change in resistance B. Change in capacitance C. Change in inductance D. Change in concentration
Explanation: In magnetic wind instruments to determine the amount of oxygen, change in temperature leads to a change in resistance. This change in resistance is measured to determine the amount of oxygen.
