John is a mechanical engineer. His first task at his job is to build any microphone of his choice. He chooses to build a dynamic
microphone. What is the major advantage offered by a dynamic microphone?
simple to construct and easy to repair
A.
B.
captures subtle nuances in a sound
OC. can pick up sounds from both sides of the microphone
OD. offers warmth to the recording sound
E. captures sounds most accurately
A dynamic microphone works on the principle of electromagnetic principle. A diaphragm is attached to a coil of wire which helps in producing sound. Responding to the sound waves, the coil of the wire is vibrated by the diaphragm. A magnetic field is created by the magnet which is present inside the coil of wire. The electrical signal is generated in response to the motion of the coil. The speed of the motion produces the amount of the current.
Since the construction of a dynamic microphone is easier as compared to any other microphone, John is likely to opt to build one.
People trust open-source software - if they can see how it works and understand it, they can help improve it and build applications using it. If these protocols were not publicly available - then nobody would have implemented services using them - so nobody would be adopting it.
