In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.
This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.

What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
What is added to a circuit to make the current smaller?
The reduction of voltage or the increase of resistance will reduce the current in a circuit.
What effect does reducing resistance have on the power in a circuit?
Since power = voltage2/resistance, reducing the resistance will increase the power of the circuit. Incidentally, power is not 'consumed'; it's energy that's consumed.
What will cause an increase in current flow in a simple series circuit?
Increase current by either increasing the voltage or decreasing the resistance.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
If current increases and resistance increases what would cause this?
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
What happens to amps when you increase the resistance of a circuit?
If you don't change the voltage between the ends of the circuit,then higher resistance in the circuit means lower current (amps).
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
Can you increase current in a circuit without change in resistance and voltage?
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
Is and example of inherent resistance?
define inherent powers and give an example Is the increase in voltage causes a greater electric resistance in a circuit? No, the resistance in a circuit does not change when voltage changes.
Describe two ways to increase the current in a circuit?
1. Increase the voltage while holding the resistance constant.and2. Decreasing the resistance while holding the voltage constant.For a fixed load, increase the supply voltage. For a fixed supply voltage, increase the load.So that there is no confusion, 'increasing a load' means reducing the resistance (in the case of a d.c. circuit) or reducing the impedance (in the case of an a.c. circuit).
