What is electrical resistance?
Electrical resistance is a fundamental concept in the field of electrical engineering. It refers to the opposition that an electrical conductor presents to the flow of electric current. In simpler terms, it is the measure of how difficult it is for electricity to pass through a material.
Definition and explanation of electrical resistance
Electrical resistance is defined as the ratio of the voltage across a conductor to the current flowing through it. It is denoted by the symbol “R” and is measured in units called Ohms (Ω). The higher the resistance, the more difficult it is for current to flow through the conductor.
Resistance occurs due to the collisions between the moving electrons and the atoms or molecules in the conductor. These collisions impede the flow of electrons, resulting in the generation of heat and a decrease in the current.
Factors affecting electrical resistance
Several factors influence the amount of resistance in a conductor. These factors include:
Length of the conductor: The longer the conductor, the greater the resistance. This is because the electrons have to travel a longer distance, increasing the likelihood of collisions.
Cross-sectional area of the conductor: The larger the cross-sectional area, the lower the resistance. A larger area allows more space for the electrons to flow, reducing the chances of collisions.
Temperature: Temperature affects the resistance of a conductor. In most materials, resistance increases with an increase in temperature. This is due to the increased vibrations of the atoms or molecules, which obstruct the electron flow.
Type of material: Different materials have different resistivities, which determine their resistance. For example, metals such as copper and aluminum have low resistivities and, therefore, low resistance. On the other hand, insulators like rubber and plastic have high resistivities and high resistance.
Units of measurement for electrical resistance
The unit of measurement for electrical resistance is the Ohm (Ω). It is named after the German physicist Georg Simon Ohm, who formulated Ohm’s Law. One Ohm is equal to the resistance that allows one Ampere of current to flow when one Volt of potential difference is applied across it.
In addition to Ohms, there are other units used to express resistance in different contexts. For instance, kilo-ohms (kΩ) represent thousands of Ohms, mega-ohms (MΩ) represent millions of Ohms, and milli-ohms (mΩ) represent thousandths of an Ohm.
Understanding electrical resistance is crucial in various applications, such as circuit design, power transmission, and electronic device functionality. By comprehending the factors that affect resistance and knowing how to measure it, electrical engineers can optimize the performance and reliability of electrical systems.

Ohm is the unit of electrical resistance in the International System of Units (SI). It is denoted by the symbol Ω (omega). The Ohm unit is named after the German physicist Georg Simon Ohm, who formulated Ohm’s law.
Ohm’s law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. This fundamental law forms the basis of electrical circuit analysis.
Relationship between Ohms and electrical resistance
Electrical resistance is the measure of an object’s opposition to the flow of electric current. It determines how much current will flow through a circuit for a given voltage. Resistance is measured in Ohms.
The relationship between Ohms and electrical resistance can be understood through Ohm’s law. According to Ohm’s law, the resistance (R) of a conductor is equal to the voltage (V) across it divided by the current (I) flowing through it:
R = V / I
This equation shows that resistance is directly proportional to voltage and inversely proportional to current. In other words, as resistance increases, the current decreases for a constant voltage.
