When a steady potential difference is applied across the ends of a conducting wire?
Current flows through the wire due to the movement of free electrons within the material, in response to the electric field established by the potential difference. The current is directly proportional to the applied potential difference, as described by Ohm's Law, provided the material's resistance remains constant.

What causes charge to flow in a conducting wire?
The flow of charge in a conducting wire is caused by the presence of an electric field. When a potential difference (voltage) is applied across the wire, it creates an electric field that exerts a force on the free electrons in the wire, causing them to move and create an electric current.
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.
How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.
What is the relationship between potential difference and capacitance in a capacitor?
The relationship between potential difference and capacitance in a capacitor is that the potential difference across a capacitor is directly proportional to its capacitance. This means that as the capacitance of a capacitor increases, the potential difference across it also increases, and vice versa.
How to calculate the potential difference across a capacitor?
To calculate the potential difference across a capacitor, you can use the formula V Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
What happens when an alternating potential difference is applied across a primary coil of a transformer?
burn or burst

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

The potential difference across a capacitor can be determined by using the formula V Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
What is the potential difference across each capacitor when the plate separation is doubled?
When the plate separation of a capacitor is doubled, the potential difference across each capacitor remains the same.
How does the energy stored in a capacitor change when the potential difference across it is doubled?
When the potential difference across a capacitor is doubled, the energy stored in the capacitor increases by a factor of four.
