flow of electrons is not visible.only it can be sensed
AnswerCurrent can only be detected through one or more of its effects. There are three effects of an electric current: heating effect, magnetic effect, and chemical effect. We use the magnetic effect (the force between currents in parallel conductors due to their magnetic effects) to define the ampere.
The flow of current through a wire is known as electrical current.
according to kcl the current flows through a wire
The flow of current through a wire increases its conductivity and decreases its resistance.
No, a current cannot flow in a wire with a free end because there is no complete circuit for the current to flow through. In order for current to flow, there must be a closed loop circuit for the electricity to circulate through.
Not true - Moving a wire through a magnetic field doescreate a current flow in a wire.false
Yes, there is a current flow through he return wire in a closed circuit. The only time there is no current flow through the return wire is when the circuit is open.
The flow of electricity is called electrical current.
A current-carrying wire has moving electrical charges, creating a magnetic field around it, while a wire with no current has static charges at rest. The current-carrying wire produces a magnetic field perpendicular to the current flow, whereas in a wire with no current, there is no associated magnetic field. Additionally, a current-carrying wire generates heat due to the flow of electrons, while a wire with no current does not.
no
it just does The thicker the wire the more space there will be for electrical current to flow. What this means is that the electrons have a lesser chance of hitting the atoms and causing resistance.
A compass can be used to find the flow of current through a wire by placing the compass near the wire. The needle of the compass will align with the magnetic field created by the current flowing through the wire, indicating the direction of the current flow. The needle will point in the direction from which the current is coming.
Current will flow more easily through a short wire compared to a long wire because the resistance of a wire increases with its length. A longer wire will have more resistance, resulting in a lower current flow compared to a shorter wire.
