Which of the following is a characteristic of a dynamic microphone?

A dynamic microphone is known for its robustness and simplicity, which includes the characteristic of being compact and not requiring an external power source. This type of microphone operates using an electromagnetic principle, where sound waves create a vibration in a diaphragm attached to a coil, generating an electrical current. Due to this design, dynamic microphones can easily function without needing batteries or phantom power, making them ideal for various applications, especially in live sound environments.

This attribute is particularly advantageous because it allows for greater mobility and ease of use in settings where power sources may not be readily available. Its durability and reliability in loud environments also contribute to its popularity. While other types of microphones, such as condenser microphones, are better suited for capturing nuanced audio details and thus require power, dynamic microphones excel in situations involving high sound pressure levels and portability.
