Verified answer
Potential Difference across a resistor is given by,
Potential Difference = Resistance * Current
= 1500 * 0.075
= 112.5 Volts

i don’t know that is my question and i’m asking for an answer
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.
What is the potential difference neede to send 2a through a 5 ohms resistor?
V=I*R -- Potential (Voltage, V) = Current (Amperage, I) * Resistance (Ohms)2A*5Ohms = 10V
What is the difference between resistance and insulation?
Resistor is a current a insulator is a not conductive and conductors can conduct.
What must be the same for any two resistors that are connected in series?
The current in each.
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 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
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
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
If a 100 ohm resistor is needed in an electric circuit carrying a current of 0.3 amperewhat resistor would you select?
A 100 ohm resistor carrying a current of 0.3 amperes would, by Ohm's Law, have a potential difference of 30 volts. A current of 0.3 amperes through a voltage of 30 volts would, by the Power Law, dissipate a power of 9 watts. You need a 10 watt resistor, alhough it is better to use a 20 watt resistor. E = IR 30 = (0.3)(100) P = IE 9 = (30)(0.3)
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.
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 much current flows through a resistor of 285 ohms if the potential difference across the resistor is 122 volts?
Use Ohm's Law, i.e., V=IR here, V=voltage I=current R=resistance
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 current across a 10k resistor and 20 volts?
First of all, current goes straight through the resistor, not across it.If the potential difference between the ends of the resistor is 20 volts,and its resistance is 10,000 ohms, then the current through it isI = E/R = 20/10,000 = 0.002 ampere = 2 milliamperes
