basically, it is hard for the current to get through. that is how the energy is spent, pushing through. and the more the resistance, the more you have to puish to get through.
Think of it as an analogy concerning the flow of water through a pipe and the flow of charge through a wire. It's harder to push water through a long pipe than it is through a short one. Also, the smaller cross-sectional area of a hose, the harder it is to push the water through. This applies to charge within a wire too.
Therefore from this analogy we can deduce that the resistance of a wire is proportional to its length as there are more atoms for electrons to collide with, concerning a longer length. In a constrasting way, resistance is inversely proportional to the cross-sectional area of the wire, so the bigger the cross-sectional area, then there will be less resistance.
Furthermore, if you are interested, there is a formula linking all of this together along with a resistivity constant that applies to all wires and varies for a particular material, but does not depend on the dimensions of the material. Be careful though, resistivity of a wire is not the resistance of a wire.

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.
Use resistance in a sentence?
The electricities resistance stops the electric circuit.
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.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
What is the electric force that makes current flow in a circuit is related to is?
The electric force that makes current flow in a circuit is related to the resistance.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
What is the resistance in a parallel circuit?
R=1/(1/ R1 +1/ R2 +1/ R3 +.........) Where R is the total external resistance(effective resistance) in an electric circuit.
What is a resistance in a parallel circuit?
R=1/(1/ R1 +1/ R2 +1/ R3 +.........) Where R is the total external resistance(effective resistance) in an electric circuit.
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.
The electric force that makes current flow in a circuit is related to the what?
The electric force that makes current flow in a circuit is related to the resistance.
What does a complete electric circuit have?
a power source, path, and load or resistance.
Will a circuit component with a high resistance will have a low electric current?
Yes
