What is Transformers: Definition and 267 Discussions

Transformers is a media franchise produced by American toy company Hasbro and Japanese toy company Takara Tomy. It follows the battles of sentient, living autonomous robots, often the Autobots and the Decepticons, who can transform into other forms, such as vehicles and animals. The franchise encompasses toys, animation, comic books, video games and films. As of 2011, it generated more than ¥2 trillion ($25 billion) in revenue, making it one of the highest-grossing media franchises of all time.
The franchise began in 1984 with the Transformers toy line, comprising transforming mecha toys from Takara's Diaclone and Microman toylines rebranded for Western markets. The term "Generation 1" covers both the animated television series The Transformers and the comic book series of the same name, which are further divided into Japanese, British and Canadian spin-offs, respectively. Sequels followed, such as the Generation 2 comic book and Beast Wars TV series, which became its own mini-universe. Generation 1 characters underwent two reboots with Dreamwave in 2001 and IDW Publishing in 2005, with a third starting in 2019. There have been other incarnations of the story based on different toy lines during and after the 20th century. The first was the Robots in Disguise series, followed by three shows (Armada, Energon, and Cybertron) that constitute a single universe called the "Unicron Trilogy".
A live-action film series started in 2007, again distinct from previous incarnations, while the Transformers: Animated series merged concepts from the G1 continuity, the 2007 live-action film and the "Unicron Trilogy". For most of the 2010s, in an attempt to mitigate the wave of reboots, the "Aligned" continuity was established. In 2018, Transformers: Cyberverse debuted, once again, distinct from the previous incarnations.
Although initially a separate and competing franchise started in 1983, Tonka's Gobots became the intellectual property of Hasbro after their buyout of Tonka in 1991. Subsequently, the universe depicted in the animated series Challenge of the GoBots and follow-up film GoBots: Battle of the Rock Lords was retroactively established as an alternate universe within the Transformers robot superhero storyline.

    Transformers in electric trains?

    I have an exam on monday and looking through the past papers I came across a question I couldn't find a suitable answer to: List the economical advantages of using a transformer in a train rather than run the overhead lines at 400V? any help would be very much appreciated... Phil N

    Why do transformers fail violently?

    I've heard that lightning or extreme heat can make transformers blow. Well, I've had it happen near me twice recently, and neither time was due to lightning (AFAIK) or heat (it's winter). One time coincided with a car hitting a pole (actually, the supporting wires that are keeping it from...

    Balancing Transformers: Info on Syncing, Load Balance & Power Loss

    Does anyone know where I can find information on Balancing Transformers. A co-worker asked me about them, and I have not had much luck finding information on them. I do know that they are used when you have duel power sources, like two generators. The transformer syncs the frequencys and...

    Iron core energy change and transformers vs. ohms law

    "Iron core energy change" and "transformers vs. ohms law" Ooh yes, I do have two question. So enjoy the meal all physics lovers! :smile: 1. If the field is increased putting an iron core inside the circuit, then what about energy conservation? (I don't know much about H-fields.) 2...

    How can you get power used from step down transformers

    Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume that your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio=1:29) receives the voltage from...

    How does a transformer regulate power between its different sides?

    Let's say that there is a transformer with 10 loops on one side (side A) and 100 loops on the other (side B). If ther is a rms 10V potential difference produce by a generator on side A, then there would be a rms 100V potential difference on side B. It would seem like the resistance through the...

    Transformers for Efficient Power Transmission | Calculating Line Loss

    A transmission line that has a resistance per unit length of 4.5*10^-4 ohms/m is to be used to transmit 5 MW over 400 miles (6.44*10^5 m). The output voltage of the generator is 4.5 kV. a) What is the line loss if a transformer is used to step up the voltage to 500 kV? b) What fraction of the...
