What is resistance?
Understand the Problem
The question is asking for a definition or explanation of the concept of resistance, likely in the context of physics or electrical engineering.
Answer
Resistance opposes the flow of electric current in a circuit.
Resistance is a measure of the opposition to the flow of electric current in an electrical circuit.
Answer for screen readers
Resistance is a measure of the opposition to the flow of electric current in an electrical circuit.
More Information
It is expressed in ohms (Ω) and depends on factors such as the material's properties, length, cross-sectional area, and temperature.
Tips
Often confused with electrical conductance which is the reciprocal of resistance. Remember, resistance stops or slows the current while conductance allows it.
