Ohms law is V=I X R. If resistance (R) is reduced and current (I) is constant, then voltage (V) must decrease. You can see from the equation that they are proportional to one another. If, however, R is reduced and V is held constant, then I must increase (I and R are inversely proportional). The only way V can increase is if either or both I and R increase.

∙ 11y agoAs one increases the resistance of the variable resistor, the potential difference/ Voltage would decrease. As additionally, according to Ohms law R =V/I, the current would increase across the variable resistor.

If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What will happen too amperage if voltage is increased and resistance remains the same?
Ohms Law says Voltage = Current x Resistance. Hence if voltage rises, so will current.
What happen to the current when the voltage increased if the resistance are constant?
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
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.
What happens to the current in a circuit if the resistance is increased?
current is the movement of charg carriers (normaly electrons) through a conductive material. the easyest way to think about it is that voltage is like a force pushing on the electrons, and resistance will push back against this. Current is then the result of these two factors. This is where we get the equation voltage=current*resistance. In answer to your question, increasing the circuit resistance will decrease the current in the circuit, as long as the supply voltage stays the same.
What happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to the current in a circuit if the resistance is increase?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
Will current increase if the voltage in a circuit is increased?
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in voltage.
If the value of resistance increased then?
If the resistance is increased the current, which is inversely proportional, decreases and, the voltage drop increases.
What will increase voltage if current is increased?
a constant resistance
What happen to the current in a circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to a circuit if the resistances is increased?
The voltage drop across each resistance will go up, and the current through the circuit will go down.
What happens when one bulb is added to a series circuit?
The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.
What happens to the voltage if the current 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.
What happens to the brightness of a bulb if the volts are increased?
The electrical potential energy increases as the voltage is increased. It further excites the filament in the bulb more than a lessor voltage would. Using good old ohm's law (Voltage = Current x Resistance), a larger voltage applied to a bulb at the same resistance increases the current proportionally and larger currents has the effect to cause higher temps in conductors
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
