Question

When AC is changed into DC to charge a laptop or phone, is the resulting voltage perfectly constant?

A. Yes
B. No, but it can be made pretty close
C. No, in fact sometime it’s negative

Answer 1

The answer is "False"

Step-by-step explanation:

In the given question one option is missing, that's why its explanation can be described as follows:

• According to wave nature, it is the DC output, which is also known as the essence of alternating current (AC).
• To convert AC to DC, we must want to see something called a rectifier.
• Its frequency DC is not a continuous but perhaps a rippling pulse that is in the way of a fixed value, that's why all the given choices were wrong.
