Answer: Electric power transmission, Electronics.
Explanation:
First we need to define what is AC and DC.
AC is basically a current that reverses or changes direction, while a DC is one that follows a specific pattern i.e one directional.
From the question on which is better suited for AC and DC,
For AC, electric power transmission is considered because of its efficiency for transmitting power over long distances and cause of it ability to be produce high voltage by transformer which is more efficient.
Also DC is considered for Electronics because of reasons like:
- accuracy and ease at which we can control it
- most modern electronic devices uses batteries, and we know batteries can't store Ac, but rather it stores DC
