If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.

∙ 13y agoSometimes. Current increases often result in increased heating, which often results in an increase in resistance, although some materials have a negative temperature coefficient (meaning as temperature increases, resistance decreases).
Wiki User
∙ 14y agoUsually the resistance remains constant. If the voltage increases, the current increases too.
Wiki User
∙ 12y agoIf the voltage is kept constant then increasing the resistance decreases the current. Resistance and current are inversely proportional.
Wiki User
∙ 12y agoOhm's Law: Current = Voltage divided by Resistance, so, if you increase resistance, then current decreases.

∙ 11y agoIn an electrical circuit, if total resistance in the circuit is increased, then the amount of current in the circuit decreased.

How does increasing the resistance affect the current?
Increasing resistance decreases current.
Does increasing the voltage across a resistor increase the electric current through the resistor?
Resistance is not affected by either voltage or current. It is determined only by the cross-sectional area, length, and resistivity of the material. As resistivity is affected by temperature, resistance is indirectly affected by temperature.In the so-called 'Ohm's Law' equation, resistance is a constant. So, if you increase voltage, the resistance remains constant, and the current would increase in proportional to the voltage.
You are monitoring electric current in a circuit. you notice the voltage increasing this mean's that?
Ohm's Law states that the current (I) flowing in a circuit is directly proportional to the applied voltage (E) and inversely proportional to the circuit's resistance (R).I = E/RAnother way of stating Ohm's Law is that the applied voltage (E) is directly proportional to both the current (I) and the resistance (R).E = IxR.So, if the voltage (E) is increasing, then either:if you know the resistance (R) is staying constant then the current (I) must be increasing - which you would see because you are monitoring it! or, if the current (which you are monitoring) is actually staying constant, then, for the voltage to be able to increase:the circuit's resistance must be increasing orthe increasing voltage could be caused by a combination of both increasing current and increasing resistance!
How does load current vary with the load resistance?
Their relationship is only dependent on the voltage lost across that resistor; voltage equals resistance times current, so increasing the current for a given voltage will require a decrease in the resistance, and vice versa.
What happens when you increase the current to a solenoid?
increasing the voltage increases the current. this is because when you increase the voltage you make the pressure that is pushing on the current (which is making it move) greater, therefore increasing it. <<>> Ohms law states that, the current is directly proportional to the applied (EMF) voltage and inversely proportional to the resistance in a circuit. The formula you are looking for is I = E/R. You supply some figures for Voltage (E) and Resistance (R).
Would increasing the resistance increase electric current?
no
What happens to the electric current in a wire when voltage is increaced?
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
What will always increase voltage?
increasing resistance and keeping current constant
What will cause an increase in current flow in a simple series circuit?
Increase current by either increasing the voltage or decreasing the resistance.
When a wire is made smaller the resistance increases. what happens to electric current?
increase
What actions will always increase voltage?
increasing resistance and keeping current constant
How does the increasing the resistance affect the current?
Increasing resistance decreases current.
How does increasing the resistance affect the current?
Increasing resistance decreases current.
Does increasing the voltage to an electric heater increase the amperage it draws?
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.
How can you increase a current in a wire?
Ohm's law. Current is directly proportional to the applied emf and inversely proportional to the resistance in the circuit.
Does increasing the voltage across a resistor increase the electric current through the resistor?
Resistance is not affected by either voltage or current. It is determined only by the cross-sectional area, length, and resistivity of the material. As resistivity is affected by temperature, resistance is indirectly affected by temperature.In the so-called 'Ohm's Law' equation, resistance is a constant. So, if you increase voltage, the resistance remains constant, and the current would increase in proportional to the voltage.
What would be the effect of increasing the voltage of the battery?
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
