Energy as heat
one volt applied across one ohm of resistance causes a current flow of one
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will cause an increase in resistance.
Think of it like this: Friction causes you difficulty in pulling heavy objects on a carpet. This frictional force is similar to electrical resistance. It is one of two ways to define how easily electricity will travel through an electrical element.
yesAnswerNo! Resistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance.These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase.For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface of a conductor which acts to reduce the effective cross-sectional area of that conductor. So, frequency can also indirectly affect resistance.

increased electrical resistance
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
Air resistance causes friction and slows an object.
An electric iron has a heating element that offers electrical resistance. The resistance causes friction to occur in the electrons and causes a heating effect.
