In a normal MI instrument, a non-inductive series resistance is added as a multiplier element. The resultant multiplying factor is a function of frequency. Suggest a method to make this factor independent of frequency. Calculate the value of the component added, if any, in terms of normal MI parameters.
Understand the Problem
The question is asking for a method to make a multiplying factor independent of frequency in a normal magnetic induction (MI) instrument. It also requests the calculation of the value of a specific component in terms of normal MI parameters.
Answer
Add capacitor: C = L/R² to make factor frequency-independent.
To make the multiplying factor frequency-independent, add a capacitor such that C = L/R², where C is capacitance, L is inductance, and R is resistance.
Answer for screen readers
To make the multiplying factor frequency-independent, add a capacitor such that C = L/R², where C is capacitance, L is inductance, and R is resistance.
More Information
Adding a capacitor in parallel can cancel out the frequency effect due to inductance, making the resistance effectively non-reactive.
Tips
Ensure the values of inductance and resistance are accurate to calculate the correct capacitance.
