   The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction.

   What is the unit of resistance?

   • The unit of resistance is the ohm, Ω Ω. For a given voltage, the higher the resistance, the lower the current. A common component in electronic circuits is the resistor. The resistor can be used to reduce current flow or provide a voltage drop.

   Why is resistance higher than expected?

   • For this reason, the geometrical cross-section is different from the effective cross-section in which current actually flows, so resistance is higher than expected. Similarly, if two conductors near each other carry AC current, their resistances increase due to the proximity effect.
