Explain in details about the terms “alarm” and “detector”.
Explanation of Solution
Discussion:
The device which provides a warning signal is known as an alarm and it works with the help of a detector when the minimum acceptable protection level is exceeded. An alarm plays a key role in the security systems of mines, residential buildings, and industries.
Example: Smoke alarms, Heat alarms, and Carbon monoxide alarms (alarms for explosive gases).
A detector is the device which has a sensor in the circuit. Sensor responds to the physical stimulus such as smoke, heat or some explosive gases.
Example: Smoke detectors, Heat detectors, and explosive gas detectors.
An alarm works with the co-ordination of a detector which has a pre-programmed sensor for the minimum acceptable levels of smoke, or heat, and so on, based on the application of an alarm.
Conclusion:
Thus, the terms “alarm” and “detector” are explained.

- A.With the aid of a diagram, describe fringing, and explain the impact that it has on the relevant magnetic circuit parameter. B. A coil of 1500 turns give rise to a magnetic flux of 2.5 mWb when carrying a certain current. If this current is reversed in 0.2 s, what is the average value of the e.m.f. induced in the coil? C.Define Mutual Inductance.Two coils are connected in series and their total inductance is measured as 0.12 H, and when the connection to one coil is reversed, the total inductance is measured as 0.04 H. If the coefficient of coupling is 0.8, determine:The self-inductance of each coil, and the mutual inductance between the coils.arrow_forwardcomparing Lenz's law and the left hand generator rule, which of these is the more important fundamental principle?arrow_forwardExample: Electric Field and Potential Inside a Charged Sphere Problem: A sphere of radius R = 0.2 m is uniformly charged with a total charge Q = 5 μC.
