Electrical Resistance: this is one of the key concepts in the study of electricity, defined as the opposition offered by a material to the flow of electric current. Represented by the symbol
????
R and measured in ohms (
Ω
Ω) depends on such factors as the resistivity of the material, its length, and cross-sectional area. The concept of resistance is important to MDCAT students as it is a base for the analysis of circuits; it is also related to Ohm’s Law and power dissipation in electrical systems.
