Why potentiometer method is an accurate method for measuring potential difference?
Say 'emf' instead potential difference. Because while measuring the same no current is drawn and just balancing the potential across with the potential drop on the balancing length of the potentiometer wire. While balancing the galvanometer shows null deflection. So no current flows through the galvanometer. A perfect balance with the potential difference (EMF) of a cell with potential drop across that particular length.
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 potential difference across a single 4 Ohm resistor if the source voltage is 230v?
the potential difference across the single 4ohm resistor is 230volts.
When measuring voltage across a receptacle you read 120 v across black and only 20 volts across white wire?
the white wire is your neutral side (ground usually), the small potential you're measuring is bleed current
Is it true that a capacitor is initially uncharged the potential difference across it is zero?
yes
Why does the voltage reading drop in measuring the potential difference across the capacitors?
Because the capacitor discharges. so voltage across the capacitor decreases.

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.
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 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.
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.
How can one determine the potential difference across a capacitor?
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.
What is the potential difference across a 1500 ohm resistor carrying a current of 0.075 A?
Potential Difference across a resistor is given by, Potential Difference = Resistance * Current = 1500 * 0.075 = 112.5 Volts
What is the relationship between the potential difference across a capacitor and the amount of charge stored on it?
The potential difference across a capacitor is directly proportional to the amount of charge stored on it. This means that as the potential difference increases, the amount of charge stored on the capacitor also increases.
