The opposition to the flow of electrons along a conductor is known as what?

• A. Capacitance
• B. Inductance
• C. Resistance
• D. Conductance

Answer: (C)

Resistance is the opposition to the flow of electric current through a conductor. It happens because moving electrons collide with atoms in the material and face resistance from the lattice and any impurities, turning some of the electrical energy into heat. Several factors affect resistance: the type of material (materials with higher resistivity oppose current more), the cross-sectional area (a thicker conductor offers less opposition), the length of the conductor (a longer path adds more opposition), and temperature (for most conductors, higher temperatures increase resistance). In Ohm’s law terms, current = voltage divided by resistance. So higher resistance means less current for the same voltage, and more resistance tends to produce more heat if current is present. This concept is fundamental in designing circuits, fuses, and protective devices. Other terms describe different electrical behaviors: capacitance is about storing charge and opposing changes in voltage; inductance opposes changes in current due to magnetic effects; conductance is the ease with which current flows (the reciprocal of resistance).
