How do charges move through an insulated wire connected across a battery us the terms potential difference current conductor and insulator?
When a battery is connected across an insulated wire, a potential difference is created between its terminals. This potential difference causes charges to move through the conductor, resulting in an electric current. The wire acts as a conductor, allowing the movement of electrons, while the insulation prevents current from leaking out, ensuring that the flow remains contained within the wire. Thus, the effective movement of charges results in a continuous current due to the maintained potential difference.

voltmeter
Why pottential difference across different ends of the conductor is different in the series connection?
In a series circuit, the total potential difference provided by the power source is divided among the resistors. Each component experiences a portion of the total voltage drop based on its own resistance, resulting in different potential differences across each component. This is why the potential difference across different ends of the conductor is different in a series connection.
What happen is the potential difference across is double?
If the potential difference across a circuit is doubled, the current flowing through the circuit will also double, assuming the resistance remains constant. This is because Ohm's Law states that current is directly proportional to voltage when resistance is held constant.
The ratio of the potential difference across a metallic conductor to the current in the conductor is known as?
That is the resistance, measured in ohms.
Why drift velocity increase by increasing potential difference?
Increasing the potential difference across a conductor results in a higher electric field, which exerts a stronger force on the charge carriers (electrons). This causes the electrons to accelerate at a faster rate, increasing their average drift velocity through the conductor.
What analogous condition is necessary for the flow of charge?
In order for charge to flow, there must be a potential difference present across a conductor. This difference in electric potential creates an electric field that drives the movement of charge through the material.
What is the force which drives an electric current through a conductor?
An electric current is driven through a conductor by the force of voltage or potential difference applied across the ends of the conductor. This force pushes the free electrons in the conductor, causing them to move in a particular direction, thus creating an electric current flow.
What is needed for charge to flow?
In order for charge to flow, a potential difference (voltage) needs to be present across a conductor. This voltage provides the electromotive force required to push the charged particles (usually electrons) through the material. Additionally, the conductor must provide a pathway for the charge to move, typically in the form of a closed circuit.
What condition is necessary for a sustained flow electric charge through a conducting medium?
A potential difference (voltage) across the conducting medium is necessary for a sustained flow of electric charge. This potential difference creates an electric field that pushes the charges through the conductor. Without a potential difference, there would be no force to maintain the flow of charges.
