Which meter measures the potential difference in the circuit?
A voltmeter measures the potential difference between two points,whether or not the two points are in the same circuit.
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
Why the unit of potential difference and electromotive force is the same?
Because an electromotive force is a potential difference (voltage) -specifically, an electromotive force is the open-circuit or no-load potential difference of a source such as a battery or generator.
What happens to the potential difference of a bulb that burns out in series circuit?
The whole circuit fails - because the action of the bulb blowing cuts the circuit.
What is the potential difference between 2 points in a circuit called?
Voltage drop
Which meter measures the potential difference in the circuit?
A voltmeter measures the potential difference between two points,whether or not the two points are in the same circuit.
What measures the potential difference of a circuit in volts?
voltmeters
How voltmeter works?
It is connected in parallel and measures potential difference.
What is the difference between electrical potential and electromotive force?
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.
What is the advantage of a parallel circuit over a series circuit.?
In a parallel circuit, all the external resistors are supplied the same potential difference which is not possible in a series circuit. Also in a parallel circuit, every resistor or component can be individually turned on or off without affecting the rest of the circuit.
Why ammeter connects in series and voltmeter in parallel in electric circuit?
Because the ammeter measures the current flowing THROUGH the wire, butthe voltmeter only measures the potential difference between two points.
Which part of the circuit supplies the potential difference in the circuit?
A battery or a generator.
What does not provide a voltage difference in a circuit?
Wires do not provide a voltage differenceAnswerAs 'voltage' is synonymous with 'potential difference', you appear to be asking "What does not provide a potential difference difference in a circuit?", which does not make any sense!

What is the source of the electrons in a circuit?
The source of electrons in a circuit is supplied by an electric potential difference across two points . This potential difference in a circuit is called as voltage and is measured in joules per coulomb or volts.
What causes electric flow in a circuit?
Potential difference, voltage.
What device creates a potential difference in an electric circuit?
resistor
