Q & A
What is the main goal of the experiment described in the script?
-The main goal of the experiment is to modify a microwave oven transformer to generate a high current by reducing its output voltage and potentially using it for applications like melting metals.
How does the transformer in the script work?
-The transformer in the script works by converting 120 volts AC input to over 200,000 volts through its primary and secondary windings, which have different numbers of turns, resulting in a step-up voltage transformation.
Why does the person in the script decide to cut the core instead of the secondary wires?
-The person decides to cut the core instead of the secondary wires to preserve the integrity of the wires, as they believe it would be preferable not to destroy the nice wires.
What is the initial problem encountered when trying to remove the windings from the core?
-The initial problem is that the layers of the core are falling apart, but the windings are not coming out, indicating that they are tightly secured.
What is the outcome of the first attempt to generate high current with a single turn of wire through the transformer?
-The first attempt results in an output of around 1.1 volts and a current of 90 amps, which is not the millions of amps the person was hoping for.
How does the person address the issue of the wire's resistance limiting the current?
-The person decides to use thicker wire, specifically an 8-gauge wire, which has a lower resistance and can handle a higher current.
What is the maximum current the 3-0 AWG wire is capable of handling?
-The 3-0 AWG wire is capable of handling 200 amps continuously and a fusing current of 2700 amps for 10 seconds.
What happens when the person shorts the output of the transformer with the thick 3-0 AWG wire?
-When the output is shorted with the 3-0 AWG wire, the current reaches over 500 amps, melting the wire and the clamp.
How does the person in the script use the high current generated for practical applications?
-The person uses the high current to melt metals, such as a spoon and a lock pick, demonstrating the potential practical applications of the experiment.
What is the role of Skillshare in the context of the script?
-Skillshare is mentioned as a sponsor of the video, providing a platform for learning various skills, including programming, video creation, and electronics, with a 30-day free trial offered to the first thousand people who join using the link in the description.

🔧 Experimenting with a High-Current Transformer
The speaker begins by introducing an experiment involving a microwave oven transformer. The goal is to reduce the output voltage to zero while increasing the current to thousands of amps. The speaker mentions using Skillshare, a platform for learning from experts, and provides a link for a free trial. The experiment involves the primary and secondary windings of the transformer, which normally convert 120 volts AC to over 200,000 volts AC. The speaker attempts to disassemble the transformer by cutting the iron core and removing the windings, despite the difficulty due to the glue holding the core together. After much effort, the speaker manages to reassemble the transformer and test its functionality, noting the noise and magnetic field strength. The experiment reveals that the transformer does not produce the millions of amps expected, leading to further adjustments and tests.
🌟 Pursuing Higher Currents with Improved Setup
In this paragraph, the speaker continues the experiment by discussing the need for thicker wire and higher voltage to achieve the desired high current. The speaker realizes that the resistance of the transformer's secondary winding limits the current and decides to use thicker wire. After a series of tests, the speaker manages to draw over 500 amps, melting the clamp in the process. The speaker then purchases a 3-0 AWG wire, capable of handling 200 amps continuously and 2700 amps for 10 seconds, to further the experiment. The speaker wraps the short circuit with copper wire for better contact and successfully generates a high current, melting a spoon and demonstrating the potential of the setup.
🎉 Successful High-Current Generation and its Applications
The speaker concludes the experiment by successfully generating a few thousand amps using the newly acquired thick wire. The speaker reflects on the potential uses of this capability, such as creating a melting pot for metals. The speaker then transitions to discussing the value of Skillshare, a community of experts sharing their skills and knowledge across various subjects. The speaker encourages the audience to take advantage of the one-month trial to learn new skills and potentially transform their careers or hobbies. The video ends with a call to action for the audience to join Skillshare and a thank you for watching.

Highlights
The experiment involves modifying a microwave oven transformer to achieve high current output at reduced voltage.
The transformer's primary function is to step up 120 volts AC to over 200,000 volts AC.
The secondary coil has approximately 20 times more windings than the primary, which is key to the voltage step-up process.
The first attempt at modifying the transformer involved cutting the core and removing the windings.
After removing the core, the experimenter attempts to reassemble the transformer without the top casing.
Upon powering the modified transformer, a significant noise is produced, indicating the need for further adjustments.
The experimenter discovers that a single turn of wire produces an output voltage of 1.1 volts AC and can handle up to 90 amps.
By doubling the number of turns and shorting the output, the current is increased, but the wire melts due to the high amperage.
The use of thicker wire (8 gauge) allows for higher current draw without melting, achieving over 500 amps.
The 3-0 AWG wire, with a resistance of 270 micro-ohms, is capable of handling 200 amps continuous and 2700 amps for 10 seconds.
With the 3-0 AWG wire, the experiment successfully draws over 3600 amps, but the efficiency of the transformer is not super high.
The experimenter wraps the short circuit contact point with copper wire to improve contact and increase current flow.
The modified transformer is capable of melting a spoon, demonstrating its high current output.
The addition of a load, such as a spoon, affects the output current, which decreases as the load resistance increases.
The experiment concludes with the successful melting of a lock pick, showcasing the practical applications of the high current output.
The experimenter reflects on the potential uses of the high current output, such as creating a melting pot for metals.
