When using \multicols and inserting a wrapped table, how do I prevent text from being pushed to the margin (see pic)?

\textbf{\emph{Abstract} -- In Part 1, the voltage and current behavior of a rectifier circuit constructed using both diodes and an SCR box across a resistive load was examined. In Part 2, the output voltage signal of an FET box over a resistive load was examined with respect to varying duty cycle and frequency.}


\section{Introduction}


\section{Theory}


\section{Results}
In Part 1 of the lab, a two-phase AC supply was fed into two types of rectifier circuits. The first rectifier circuit was constructed out of two diodes connected in series with each phase of the voltage source, both leading to a common output resistor. The current through a single diode, as well as the voltage and current across the common resistor, are displayed in Figure 1. The current through the diode exhibits the positive half of a sine wave for half of its shape, and maintains a value of 0 for the other half. This shape reflects the fact that the diode can only be activated by positive voltage, hence the positive sine wave portion of the waveform, and will not produce any current if exposed to a negative voltage, hence the 0-value half of the waveform. The voltage and current across the common resistor, which are in phase with one another, as expected for a purely resistive element, are constantly exhibiting the positive half of a sine wave. This is due to the two-phase nature of the voltage source, because when one phase voltage is negative (hence not producing any diode current), the other will be positive. The measured values of resistor voltage, current, and power are displayed in Table 1.

The second rectifier circuit was constructed from a silicon-controlled rectifier (SCR) unit, again connected to a two-phase AC source on one end and a common resistor on the other. The measured current and voltage waveforms from this circuit are shown in Figure 2, and follow a similar pattern to that of Figure 1. However, instead of current being activated as soon as the voltage source produces positive voltage, as it was with the diode-based rectifier circuit, the SCR box exhibits a delay, leading to flat 0-value sections of the resistor voltage/current. This delay is controllable due to the fact that the SCR box is made up of thyristors, which are more controllable than simple diodes because a third terminal (the gate) must receive a signal pulse in order to allow current through. The measured values of resistor voltage, current, and power are displayed in Table 2.

I'm using \multicols for a two-column document and trying to insert tables and figures within each column using wrapfig and wraptable. However, on wraptable LaTeX decided to push the text that was supposed to come after the table all the way to the right margin (outside of the second column - see pic). I'm having a lot of trouble doing anything to fix this, any help appreciated.

Answer 1

For your reference, this is how the rebuilding-process could look like:

% check out manual at https://ctan.org/pkg/article?lang=en
% say, that you want two columns
\documentclass[11pt,twocolumn]{article}

\begin{document}
    % specify title, author etc.
    \title{Lab Report 0 - Introduction to the Laboratory}
    \author{Laboratory Section AB4}
    % show it
    \maketitle

    % here's the abstract

Hint: The User Manual for article is a bit peculiar, as it mixes both user syntax and implementation. As a rule of thumb:

• the margins will tell you the commands to use in regular Latex-code
• if in doubt, search either the index or the whole User Manual
• most frequently you'll probably only need Ch. 7 Document Markup
