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.

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 happens to materials which are poor conductors of electricity when they are forced to carry electricity?

Being a poor conductor simply means that such an object has a high electrical resistance. If a voltage is applied to such a material, only a small current will flow. Forcing a poor conductor to carry electricty will cause most of the watts to be dispersed over that conductor causing it to heat up.

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.

What happens to electrodes when electric current flows?

The electrons are forced to move in one direction (on average) through the wire, due to a voltage potential between one end of the wire and the other. The electrons are repelled away from the negative end and attracted toward the positive end. Current flowing through the wire induces a magnetic field around the wire.

When electric current flows through a metal wire?

current flows through the conductor due to the motion of the free charge carriers present in it. The more charge carriers present in the conductor, the more current flow through that conductor. No free carriers present in the insulator and hence no current flows through insulator. charge carriers causes the current flows through the conductor.
