Your question: Why is heat produced on passing the electric current?

When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat.

Why is heat produced when current is passed through a conductor?

When the conduction electrons flow through the material, the electrons transfer their energy to the conductor’s atoms through collision. Due to this transfer of energy through collision, the heat is generated in the conductor. So, the temperature of the conductor increases because of the current flow through it.

How is heat produced by an electric current?

Heating Effect of Current

When an electric current is passed through a conductor, the conductor becomes hot after some time and produces heat. … When electricity flows into the resistor, it is turned into heat. Electric currents generate heat as they pass through resistive elements of a circuit.

What is produced when electric current passes through a conductor?

Electromagnetism is produced when an electrical current flows through a simple conductor such as a length of wire or cable, and as current passes along the whole of the conductor then a magnetic field is created along the whole of the conductor.

What is produced when an electric current is passed through a conductor?

Answer: An electric current is passing through a conductor which becomes hot after some time and produces heat. This is due to the conversion of some of the electrical energy that passes through the conductor, into heat energy. This effect of electric current is called the heating effect of current.

How electric current is produced?

To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. … The flow of electricity can be likened to a flow of water through a pipe.

Why does the current flow from positive to negative?

The particles that carry charge through wires in a circuit are mobile electrons. The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field.

What are the factors on which heat produced due to a current flowing through a conductor depends?

The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat. The time, t for which current flows.

What is needed for heat to flow through a conductor?

The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length, and the properties of those materials.
