Description : What arc the errors occurring in measuring devices due to stray magnetic field and temp '? Explain how to compensate them.
Last Answer : 1. Error due to stray magnetic fields- Main magnetic field gets disturbed by external magnetic fields known as stray magnetic fields. 2. Compensation technique To avoid this error, ... resistance alloy having a negligible resistance temp coefficient in the ratio of 1:10 for pressure coil
Description : What are examples of telecommunication devices?
Description : Explain the concept of initial and final conditions in switching for L and C.
Last Answer : i) Inductor: The current through an inductor cannot change instantly. If the inductor current is zero just before switching, then whatever may be the applied voltage, just after switching the inductor ... open-circuit. The initial and final conditions are summarized in following table:
