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
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.
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.
If as more resistors are connected in series with the first what happens to the potential difference across each resistor?
adding resistors to a string will have the effect of decreasing each resistor voltage drop.
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
How are you going to arrange a circuit if you want to measure the potential drop across a resistor?
Connect a power source to the resistor (+ve terminal to one side of the resistor and -ve terminal to the other) then connect a voltmeter in parallel with the resistor. The reading on the voltmeter will provide a measure of the potential difference across the resistor (ie: the voltage drop across it).

How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
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
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 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.
What is the potential difference across a resistor that dissipates 24 W of power and has a current of 3 A?
Work it out yourself. PD=P/I, Where PD=Potential Difference, P=Power & I=Current
What will be the potential difference across a 50Ω resistor if a current of 500mA is flowing through it?
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
Three identical bulbs are connected in parallel across a 12-V battery If one of the bulbs were removed from its socket then the potential difference measured across the empty socket would be?
12V. Every resistor in a parallel circuit shares the same voltage. It is the current that gets divided.
If as more resistors are connected in series with the first what happens to the potential difference across each resistor?
adding resistors to a string will have the effect of decreasing each resistor voltage drop.
