No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.

What are the three great truths about circuitry?
1. The sum of the component voltage drops in a series circuit is equal to the voltage at the source.Vs=V1+V2+...+Vn (s=source, n=total number of voltage drops in the circuit)2. The greater the resistance imposed by a component, the greater the voltage drop across it.Larger resistor=larger voltage drops, Smaller resistor=smaller voltage drops3. In a series circuit, the percentage of resistance contributed by a component is equal to the percentage of voltage dropped by that component.
Is it true that for the same resistance the greater the voltage the greater the current?
true
What happens if capacitance of circuit is more than resistance?
Resistance is a completely different quantity to capacitance, resistance being measured in ohms and capacitance in farads. So they are 'apples and oranges'. You should be asking, 'What happens if capacitive reactance (in ohms) is larger than resistance?'. And one answer would be that the phase angle will be greater than 45 degrees. There are other answers, too, but it depends what you want to know,
Do conductors have low resistance?
Conductors have low resistance. Recall Ohm's law. The higher the conductor resistance, the greater the voltage drop along the conductor, and the less voltage that is available for the load. The conductor resistance is a resistance in series with the load. Also, higher conductor resistance results in more electrical power being converted into heat, warming up the conductors. This is calculated with the formula P=I2R. The greater the resistance, the greater the power wasted heating the conductors.
What is the power factor of choke coil?
All one can say without more information is that it is less than 1 and greater than zero.
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.
If Greater resistance is put into a circuit the brighter the bulb?
no
If the resistance changes in a circuit the amperage will also change?
I=V/R The smaller the resistance the greater the amperage.
In any parallel circuit within a combination circuit the greater current will flow through the?
lowest resistance
What makes an electric cuchi?
An electric current relies on several things. First, there must be a continuous connection of conductors. Then there must be a voltage or a potential difference between two parts of a circuit. It is the voltage that causes electrons to move, so generating an electric current. The amount of current depends on both the voltage and the resistance of the circuit. The higher the voltage, the greater the current. The higher the resistance, the lower the current will be.
What happens in a circuit when the resistance gets greater?
Flow of current decreases proportionately.
Three ways which resistance of a wire can be increased?
You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).
Which direction does the parachutist go if gravity is greater than air resistance?
The parachutist will go down, of course. If gravity is greater than air resistance, then the parachutist would accelerate (his speed would increase). This would increase air resistance, up to the point where gravity and air resistance are in balance.
What happen to the current when the voltage is greater than or equal to 6 volts?
The current is greater than or equal to (6) divided by (the effective resistance of the circuit).
What arrangement of three cells would result in the greatest electric current?
I haven't studied this for awhile, but... I assume by cell, you mean a voltage supply, like a battery. It depends on what else is in the circuit. If your circuit has a typical amount of resistance, then connecting the cells in series (as opposed to in parallel) will result in the largest voltage. Higher voltage means greater current across a resistor. However, if the resistance of the circuit is very low (like in a short circuit), then your batteries' own internal resistance may be the most significant factor, and batteries arranged in parallel may be able to sustain a higher current.
What happens when you increase the current to a solenoid?
increasing the voltage increases the current. this is because when you increase the voltage you make the pressure that is pushing on the current (which is making it move) greater, therefore increasing it. <<>> Ohms law states that, the current is directly proportional to the applied (EMF) voltage and inversely proportional to the resistance in a circuit. The formula you are looking for is I = E/R. You supply some figures for Voltage (E) and Resistance (R).
What makes small and large electric currents?
The combination of supply voltage and load. For any given supply voltage, the greater the load (i.e. the lower its resistance), the greater the resulting current.
