Does increasing potential difference increase resistance?
Niamhcarter9
Resistance is due to a property specific resistance of material. In no way resistance depends on the voltage applied. This is the case of ordinary conductor. But in case of semi conductor or insulator there may be chances to get a variation of conductance and hence resistance due to potential applied.

How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
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 potential difference between the terminals of a cell in a circuit fixed or does it depend on the components that are connected in the circuit?
All cells have internal resistance. The value is very small when the cell is fresh. The value increases slightly and slowly as the cell discharges. So the potential difference across the cell will not noticeably change when a load is initially connected. As the cell becomes more discharged, the drop in potential difference upon connecting a load will increase. The point at which the cell is no longer any use depends on the minimum voltage which the load requires, and the current required by it.
Does thickness of a metal affect its electrical resistance?
Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.
What is the difference between PTC and NTC resistors?
positive temperature coefficient vs. negative temperature coefficient resistance increases or decreases with increase of temperature, respectively.
Will increasing the conductor thickness increase resistance?
No. A thicker conductor will lower resistance.
Would increasing the resistance increase electric current?
no
How does gravitational potential energy of an object increase?
On Earth, Gravitational Potential Energy (GPE) would increase with an increasing altitude.
What will always increase voltage?
increasing resistance and keeping current constant
How does increasing the wire gauge from awg 22 to awg 26 generally effect resistance?
Resistance will increase.
What actions will always increase voltage?
increasing resistance and keeping current constant
How does an open parachute increase the air resistance of a falling?
by increasing surface area
How did increasing the stimulus voltage in the simulation affect the action potential?
Increasing the stimulus voltage in the simulation affect action potential mainly because increasing the current will automatically increase the voltage.
When the potential is high the current passing through a conductor it is also high true or false?
I think you mean when the 'potential difference' is high, is the current also high? The answer is that it depends on the impedance (a.c.) or resistance (d.c.) of the circuit. If this remains constant, then raising the potential difference will cause the current to increase too.
How does an open parachute increase the air resistance of a falling skydiver?
by increasing surface area
How does a open parachute increase the air resistance of a falling skydiver?
by increasing surface area
What affects potential?
Temperature is directly proportional to kinetic energy (potential energy).eg. increase the temperature, you increase the kinetic energy of the molecules, hence you're increasing the potential energy of them.
