Current decreases
When voltage remains constant and resistance increases the current in the circuit will reduce.
More information
V=IR
where V is voltage,
I is current and
R is resistance.
From the above equation,
R=V/I, and hence resistance is indirectly proportional to current.
Therefore, an increase in resistance would have the effect of decreased current.
NB: this holds true only as long as the voltage remains constant.
Another opinion
However, this is only true in the case of a circuit connected in series.
When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.
Yet another view
No, that's not stated right.
If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...
Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".
So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.
Actually, the second opinion is correct
In a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.
In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
current decreases and resistance increases
nothing
As the resistance is reduced across the same voltage, the current increases.
When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
it increases
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
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.

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
"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.
In a circuit, as the voltage increases, the current also increases, assuming the resistance remains constant, according to Ohm's Law (I = V/R). This relationship indicates that higher voltage pushes more electrons through the circuit, resulting in greater current flow. However, if the resistance changes, the effect on current may vary accordingly. In cases with non-linear components, the relationship between voltage and current can be more complex.
