The electrical resistance of the material.
All materials have some electrical resistance except for superconductors.
A conductor is a material that allows the flow of electrical current due to the presence of free electrons that can move easily through its structure. Materials like metals are good conductors because they have a high density of free electrons that can carry electric current.
A metal pen is a conductor because it allows electric current to flow through it easily due to the free movement of electrons within the metal. This property makes it a good material for making circuits and conducting electricity.
Polythene is considered an insulator. It has low electrical conductivity, meaning it does not allow electric current to flow easily through it. This property makes it useful for electrical insulation purposes.
Rubber is generally considered to be an insulator rather than a conductor of electricity. Rubber has a high resistance to electrical current, so it does not allow electricity to flow easily through it. This property makes rubber useful for insulating wires and cables to prevent electric shocks.
Iron is a good electrical conductor. It has high electrical conductivity, allowing it to effectively carry electrical current. This property makes iron useful in various electrical applications and devices.

A: Nickel has a very low point melting value which for that fact makes undesirable as conductor.
Resistance in the circuit makes it difficult for current to pass through.
Ohm's Law states that Voltage = Current x Resistance. Usually written as V = I x RAnswerNot Ohm's Law, which makes no reference to resistance.Ohm' Law states that 'the current flowing through a conductor is directly proportional to the applied voltage, providing the temperature of the conductor remains constant'.
A metal pen is a conductor because it allows electric current to flow through it easily due to the free movement of electrons within the metal. This property makes it a good material for making circuits and conducting electricity.
air becomes good conductor during lightning and thunderstorm as usually it is a bad conductor because when there is lightning the lightning bolt travel through air,an electron flow takes place. this electron flow through the air leaves behinfd it a little hollow channel in the air it produces charge and air gets charged with this and becomes good conductor during lightning and thundestorm. thanx.......... prachi singh india
it makes a rainbow!
An electric current is the movement of the conduction band electron "gas" in a conductor. This can be induced in various ways:Application of a voltage difference across the conductor.Having magnetic flux lines "cut through" the conductor, which will push the electron "gas" perpendicular to the plane the flux lines "cut".Connecting the conductor to 2 dissimilar metals and placing the metals in an electrolyte. Corrosion of one of the metals will cause current in the conductor.etc.
The term, 'overcurrent', describes either an 'overload current' or a 'short-circuit current'.An 'overload current' is a current that is higher than a circuit's 'rated current'. For example, if you have too many loads plugged into the same circuit, then the resulting current is an 'overload current'.A 'short-circuit current' is a large current resulting when a line ('hot') conductor accidentally makes contact with either a neutral conductor or an earth (ground) conductor.
Polythene is considered an insulator. It has low electrical conductivity, meaning it does not allow electric current to flow easily through it. This property makes it useful for electrical insulation purposes.
Hydrogen peroxide is a good conductor of electricity because it contains ions that can move freely, allowing electric current to flow through it. The presence of these ions in the solution makes hydrogen peroxide able to conduct electricity.
