Is joined in circuit current is flow through?
WHEN DOES CURRENT FLOW IN A CIRCUIT? In a complete circuit, the electrons flow from the negative terminal (connection) on the power source, through the connecting wires and components, such as bulbs, and back to the positive terminal.
Can charge flow occur through an equipotential surface?
The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. This implies that a conductor is an equipotential surface in static situations. There can be no voltage difference across the surface of a conductor, or charges will flow.
Will electric current flow if there is a gap between the conducting wire?
Answer: No. Electric current will not flow in a circuit in which there is a gap between them. This is because gap contains air and air does not conduct electricity.
Why can’t two electric field lines cross?
Electric field lines cannot cross. This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
How electric current passes through a wire?
electrons
An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.
How does electricity flow through the wires in a circuit?
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.
Why do two equipotential surfaces never intersect?
They cannot intersect each other because two different equipotential surfaces have different electric potential. It means the electric field intensity is perpendicular to the surface.
What is the relationship between equipotential lines and electric field?
Equipotential lines are always perpendicular to the electric field. In three dimensions, the lines form equipotential surfaces. Movement along an equipotential surface requires no work because such movement is always perpendicular to the electric field.
