Electric current passes through a conductor when a voltage is applied across it, creating an electric field that pushes charged particles (electrons) through the material. The electrons move in response to this field, flowing from areas of higher voltage to areas of lower voltage. The amount of current that passes through the conductor depends on the material's conductivity and the applied voltage.
What else can I help you with?
What does electric current produce?
Electric current produces magnetic fields around the conductor through which it flows, according to Ampère's law. Additionally, electric current also generates heat due to the resistance of the material through which it passes.
Whichof these is the best definition for electrical current?
Electrical current is the flow of electric charge in a circuit, typically carried by electrons through a conductor. It is measured in amperes (A) and indicates the rate at which electric charge passes through a given point in a circuit over time.
Who found heating effect of electric current?
The heating effect of electric current was discovered by James Prescott Joule in the mid-19th century. Joule's experiments showed that the temperature of a conductor increases when an electric current passes through it.
What happens to a wire when and electric current passes through it?
When an electric current passes through a wire, the wire heats up due to the resistance in the material. The current causes electrons to flow through the wire, creating a magnetic field around it. This effect is used in electromagnets and electric motors.
When current passes through a conductor what makes the conductor heat up?
When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
When ac passes through a conductor which fields are produced a magnetic field or an electric field?
when ac passes through a conductor, the field produced is an electric field

Where does matter charcoal go while burning?
graphite is a non metal and an element and because it is a weak conductor of electricity it lets electric current and heat flow through it and when electric current passes through it it faces resistance and glows.

What does a coil do?
Produce a magnetic field as electric current passes through it.
What will happen to an electric wire if a large current passes through it?
It will get hot.

When current passes through a conductor what makes the conductor heat up?
When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
What is the relationship between electricity and magnetism with an electromagnet?
Oesterd discovered that when an electric current flows through a conductor a magnetic field develops around the conductor. So when you switch on the electromagnet a current passes through a solenoid generating a magnetic field which can be controlled by either forming more or less loops or increasing/decreasing the amount of current passing through the solenoid.
