What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?

If resistance increases and voltage stays the same, then current decreases.
Ohm's Law: Current equals Voltage divided by Resistance.

∙ 13y agoBy Ohm's Law, current is equal to voltage divided by resistance, so if resistance increases, with voltage staying the same, current must therefore decrease.

If the current increases what happens to resistance?
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will cause an increase in resistance.
In a circuit is current proportional to resistance?
Ohms law is: I = V / R (current = voltage / resistance)... where if the voltage or resistance changes then the current will change. ... the current and resistance is a inversely proportional linearly relationship ...this means that if the resistance doubles then the current halfs, if the resistance halfs then the current doubles, etc...hope this helps
What happens to the resistance of the bulb as the current passing through it increases?
Yes but very slightly,because temperature coefficient of bulb element is very low.
What happens to the current flow in a circuit when a second component is added in series?
The total current decreases.According to the Ohm's law the current & the resistance are inversely proportional so when we put a load in series with the existing load, the resistance of the circuit increases therefor the current decreases.
What happens to current flow when the resistance is higher than normal?
For a specific voltage, current flow is inversely proportional to resistance.
What happens to the current as the resistance decreases?
it increases
When a wire is smaller the resistance increases What happens to the electrical current?
increase
What happens to the current in a filament is replaced by a longer wire?
resistance increases
What happens when a part of a parallel circuit is disconnected?
current decreases and resistance increases
What happens with electric current when applying the same voltage the resistance of the circuit is reduced?
As the resistance is reduced across the same voltage, the current increases.
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
What happens to current flow if circuit resistance increases and voltage remains the same?
nothing
When a wire is made smaller the resistance increases. what happens to electric current?
increase
What happens to voltage when resistance increases?
Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit." <<>> if resistor exists, resistance decreases according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance it means as current increases, voltage increases. resistance increases, current decreases so as voltage if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter
When the resistance in a circuit increases what happens to the current flow?
"Ohms Law" defines resistance (R) as the the ratio of voltage (V) to current (I).R = V/IIf you move those variables around, you can get the formula:I = V/RSo you can see that when resistance increases, current flow will decrease.CommentResistance is most definitely not defined as 'the ratio of voltage to current', although that ratio may tell you what it happens to be.Resistance isn't a variable in the Ohm's Law equation. It is a constant because it is unaffected by either current or resistance.
If the current increases what happens to resistance?
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will cause an increase in resistance.
