What happens if a large current is forced through a high resistance wire?

A large amount of energy, calculated as the voltage difference across the wire, will be expended in that section of wire. This would most likely cause it to glow and/or create a lot of heat, which could possibly melt the wire and break the circuit (this is the principle any fuse is based on - a fuse is a low resistance wire that has a low melting temperature, so a "large" current will cause the fuse to heat excessively, melting the conductor).
A light bulb is exactly this - a "high resistance" wire (or filament), where relatively large current is pushed through a very small cross section of wire, causing it to glow.

What does forced commutation mean?
The term "Forced commutation" is used when a thyristor is turned off using external components. If a thyristor is used in a DC circuit, when first turned on, it will stay on until the current goes to zero. To turn off the thyristor it is possible to use a Forced commutation circuit. The circuit creates a reverse voltage over the thyristor (and a small reverse current) for a short time, but long enough to turn off the thyristor. A simple circuit consist of a precharged capacitor and a switch (e.g. another thyristor) parallel to the thyristor. When the switch is closed, the current is supplied by the capacitor for a short while. This cause a reversed voltage over the thyristor, and the thyristor is turned off.

How glue gun heating element works?
A glue gun heating element consists of a metal rod wrapped with a high-resistance wire, such as nichrome. When electricity passes through the wire, it generates heat due to electrical resistance. This heat is transferred to the metal rod, which then heats up the glue stick in the gun to melt it for application.
What happens to materials which are poor conductors of electricity when they are forced to carry electricity?
Poor conductors of electricity will offer high resistance to the flow of electricity when forced to carry it. This resistance causes the material to heat up, potentially leading to damage or breakdown if the current is too high. Depending on the material, it may also experience chemical changes or physical breakdown due to the electrical stress.
What Is Resistance In Swimming?
Resistance is drag caused naturally by the water being forced around your body and swimsuit.
Can you saturate a CT with the secondarys shorted?
A CT becomes saturated when the induced secondary voltage is beyond the capabilities of the CT. Yes it is possible, if enough current is forced through the secondary to raise the voltage beyond the CT capability curve. Remember the CT has inherent resistance due to the secondary winding. That said, to saturate strictly based on the CT resistance is unlikely. But it is still theoretically possible.

What is power dissipation in resistance?
The power P dissipated by a resistor will leave the resistor in the form of thermal energy (heat). It will get hot due to the fact that the material it is made of opposes current flow, and when current is forced through it by a voltage source, it gets hot in response. Resistance R could be thought of as "electrical friction" in many cases. Resistance is measured in ohms, voltage V in volts and current I in amperes (amps). The power in watts dissipated by a resistor with the value R will be the square of the current through it times its resistance. P=I2R The power in watts dissipated by a resistor with the value R will be the square of the voltage drop across it divided by its resistance. P=V2/R Because E means energy we take V for voltage. The power in watts dissipated by a resistor with the value R will be the voltage drop across it times the current flow through it. P=IV All three statements are true, and they all say the same thing. The mathematician might say that the variable P is being expressed in terms of the variables I, V and R. As all the statements are true, it can be said that P=I2R=V2/R=IV.
