How will the current change if the voltage in a circuit is reduce while the resistance remains constant?

The current will drop. Y??
See it this way - resistance is something that opposes current flow. Voltage is the one that helps the current to get across the resistance. So if u have a high resistance, u need a high voltage to get the same current across.
But all the values are solely dependent on the output required.
Hope that helps.

∙ 15y agoThe formula you are looking for is I = E/R. Amps = Voltage/Resistance. Put in some values and you will find the answer.

∙ 13y agoIf you lower the resistance by half, then the current increases 2x

∙ 11y agoAssuming the voltage is constant, the current will increase. This is given by Ohm's Law: V=iR

∙ 10y agoIn order for BOTH Current AND Resistance to DECREASE, the Voltage in the circuit must DECREASE as well. Power consumption (Wattage) would DECREASE.

If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
Will doubling the resistance in a circuit halve the current if voltage is held constant?
If resistance is halved while voltage remains constant, the current will double.
When current remains constant and resistance increases the voltage in the circuit will?
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
As the DC voltage applied to a circuit decreases what will the current do?
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
If the resistance decreases in a circuit when the voltage remains constant the current will?
Current will increase
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * 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 doubling the resistance in a circuit halve the current if voltage is held constant?
If resistance is halved while voltage remains constant, the current will double.
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
What is happening if energy input remains constant and voltage remains the same in a circuit but the current decreases?
The resistance is decreasing
When current remains constant and resistance increases the voltage in the circuit will?
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
If voltage remains constant and resistance decreases current flow?
the current will increase because of a lower level of resistance , hence more current will flow- easily
Does current effect the resistance in an electric series circuit?
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
As the DC voltage applied to a circuit decreases what will the current do?
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
