Using ohm's law, V=IR then R=V/I =6/0.0015=4000 ohm = 4k ohm resistor.
4000 ohm
__ Ohms resistance is required to limit the current to 1.5mA if the potential drop across resister is 6V.
9 ohms
Potential Difference across a resistor is given by, Potential Difference = Resistance * Current = 1500 * 0.075 = 112.5 Volts
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
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.
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
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

A resistor's resistance is measured in ohms. The higher the resistance the less current will flow with a constant voltage applied across the resistor. In terms of Ohm's Law Voltage = Current x Resistance.
You can measure it, but you can't calculate it. That's why the resistance of a resistor is always printed on it, either in numbers or in color bands. Without that marking, the resistor is pretty useless. If it accidentally missed being marked during manufacture, it would be either discarded, or sold surplus for bubkes.
Use Ohm's Law, i.e., V=IR here, V=voltage I=current R=resistance
The voltage of a battery goes as the current times the resistance (V=IR). Because the voltage is being held constant, the resistor that draws the most current will have the lower resistance.
IF there is a Resistor
