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
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.
A possible/probable unit is Watts.
V=I*R -- Potential (Voltage, V) = Current (Amperage, I) * Resistance (Ohms)2A*5Ohms = 10V
Resistor is a current a insulator is a not conductive and conductors can conduct.
The current in each.
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

Work it out yourself. PD=P/I, Where PD=Potential Difference, P=Power & I=Current
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
No current flows when the the voltage is zero.
22ma. E=R/I
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)
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
A possible/probable unit is Watts.
Use Ohm's Law, i.e., V=IR here, V=voltage I=current R=resistance
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.
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
