What is the potential difference in electricity?
The potential difference in electricity is the Electromagnetic Force, in Volts, measured across the two wires that make the circuit.
Is potential difference directly or inversely proportional to resistance?
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
What happen is the potential difference across is double?
If the potential difference between the ends of any conductor is doubled, then the current through the conductor is also doubled.
What stops the current flowing in a circuit?
Current will cease when either or both the potential difference across the load is Zero or when the load, itself, is Infinite in resistance or impedance.
What is the difference between resistor and resistance?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors
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
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.
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
Is the sum of the potential differences equal to the voltage applied across them?
Yes for a closed circuit
How is the potential difference across a resistor measured?
by using voltmeter
What is the potential difference across the terminals of a battery?
Please share your answer?
What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
What is the potential difference in electricity?
The potential difference in electricity is the Electromagnetic Force, in Volts, measured across the two wires that make the circuit.
What is difference between voltage and potential difference?
they are both the same thing but it is probably better to say potential difference as it is easier to understand. (since it is the DIFFERENCE across two points)
Why must a light bulb be connected to both ends of a battery to light up?
For current to flow through the lamp, there must be a potential difference (voltage) applied across opposite ends of that lamp.
