What else can I help you with?
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.
A step-down transformer has 525 turns in its secondary and 12500 turns in its primary If the potential difference across the primary is 3510 V what is the potential difference across the secondary?
The potential difference across the secondary coil will be 147.42 Volts
How is electrical current produced?
A potential difference (volts) is set up between the two ends of a conductor. If there are any electrons available to move, then their negative electric charges persuade them to move away from the more negative potential and toward the more positive potential, resulting in current.
What is the potential difference across a single 4 Ohm resistor if the source voltage is 230v?
the potential difference across the single 4ohm resistor is 230volts.
Is it true that a capacitor is initially uncharged the potential difference across it is zero?
yes
Name a device that helps to maintain a potential difference across a conductor?
volt meter is the device that helps to maintain a potential difference across a conductor
What are the factors that maintain the flow of charges in conductor?
Factors that maintain the flow of charges in a conductor include the presence of an electric field, the availability of mobile charge carriers (such as electrons in metals), and the absence of significant resistance that would impede the flow of charges. Additionally, maintaining a potential difference across the conductor helps to sustain the flow of charges.
How is the potential difference maintained across the end of the conductor?
That's the job of the battery or other power supply.
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.
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.
A step-down transformer has 525 turns in its secondary and 12500 turns in its primary If the potential difference across the primary is 3510 V what is the potential difference across the secondary?
The potential difference across the secondary coil will be 147.42 Volts
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.
