AI Thread Summary
The discussion focuses on applying induction heating principles to a transformer by short-circuiting its secondary, with the goal of generating significant heat. However, this approach is cautioned against, as standard transformers are not designed for such use and can be dangerous. Instead, examples like induction cooktops are provided, where a coil generates eddy currents in a pot, effectively creating a transformer with a shorted secondary. Participants are encouraged to clarify their intentions and explore safer, more effective heating methods. Overall, the conversation highlights the importance of understanding transformer design and appropriate applications for induction heating.

our aim is apply the principle of induction heating in the transformer by short circuiting the secondary of the transformer... the heat produced from it should produce large amount of heat ... if u have any idea pls reply me... also suggest tha rating of the transformers and other instrument

thanks... if u have any other send it

Your question makes no sense as written. It may be an issue with language translation software. You don't use a standard transformer as a heater. What kind of heater are you trying to make? Do not short the secondary of a standard transformer -- they are not generally designed to handle that.
 
Try reading this:

http://en.wikipedia.org/wiki/Induction_heating

You can get kitchen stoves where the cooking surface is just glass and the iron pots sit on top of this and get heated from a coil under the glass causing eddy currents in the iron pot.

The coil plus the pot make up a transformer with a shorted secondary.

They seem to be very effective although you might expect them to be very lossy.

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
