Power supply: Water pump, producing pressure at its output valve.
Resistor: A section of pipe. Flow of water loses energy on the way through, due to friction with the pipe's interior wall.
Potential difference: Difference in water pressure between the beginning and end of the pipe section.

What device creates a potential difference in an electric circuit?
resistor
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
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 is a resistance furnace?
An electric furnace in which the heat is developed by the passage of current through a suitable internal resistance that may be the charge itself, a resistor embedded in the charge, or a resistor surrounding the charge.
What is the difference between resistor and insulator?
A resistor lets electricity flow, but in a calculated restriction of amount. An insulator prevents electricity from flowing across it - period.
What device creates a potential difference in an electric circuit?
resistor
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 does the potential difference in the resistor change as the current through it changes?
The potential difference accross the resistor changes mainly due to gradual increase accumulation of electrons in the lower potential region which will in turn affect the potential gradient as the current flows through the resistor
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
How is the potential difference across a resistor measured?
by using voltmeter
When the current traveling through a resistor is increased what happens to the voltage that travels through the same resistor?
Your question reveals fundamental misunderstandings about the nature of electricity.'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.
How much current is in a resistor of 1.8 k if the potential difference across the resistor is 4.0 X 10 V?
22ma. E=R/I
Where is the resistor in an electric stove?
What is a electric stove resistor made
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
What is possible unit for the product VI where V is the potential difference across a resistor and you is the current through the same resistor?
A possible/probable unit is Watts.
How do you connect and measure voltage using a voltmeter?
with a voltomiter
If there is a potential difference of 12 V across a resistor with 0.25 A current in it the resistance if the resistor is?
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
