2. Including a full-wave rectifier in an AC circuit will yield a(n) _______ current.

A. continuous alternating
B. continuous direct
C. intermittent direct
D. intermittent alternating

I think B is what you're looking for; however, without filtering installed the continuous current is not constant. I would have been happier with the description of "varying direct".

To determine the correct answer, let's first understand what a rectifier does and how it affects the current in an AC circuit.

A rectifier is an electronic device that converts alternating current (AC) into direct current (DC) by allowing the flow of current in only one direction. It consists of diodes that block the current in one direction and allow it to flow in the opposite direction.

In the case of a full-wave rectifier, it utilizes four diodes and converts both the positive and negative halves of the AC waveform into a continuous, positive DC waveform. It achieves this by using two diodes to block the negative half of the AC waveform and two diodes to block the positive half, resulting in a continuous, unidirectional flow of current.

Based on this information, we can now determine the answer:

A full-wave rectifier converts the AC waveform into a continuous, positive DC waveform. Therefore, the correct answer is B. continuous direct current.
