Potential difference
The syllabus for AIIMS (All India Institute of Medical Sciences) entrance exams typically covers the fundamental concepts of physics. One of the topics that is included in the physics syllabus is “Potential Difference.”
Potential difference, also known as voltage, is an important concept in physics and electrical engineering. It refers to the difference in electric potential between two points in an electric circuit. The potential difference is measured in volts (V) and represents the work done per unit charge to move a charge between the two points.
Here are some key points related to potential difference that you should be familiar with:
- Electric Potential: Electric potential is a scalar quantity that describes the electric potential energy per unit charge at a specific point in an electric field. It is denoted by V and measured in volts (V).
- Definition of Potential Difference: The potential difference between two points in an electric circuit is defined as the work done per unit charge in moving a positive test charge from one point to the other against the electric field. Mathematically, potential difference (ΔV) is given by the equation ΔV = V₂ – V₁, where V₁ and V₂ represent the electric potentials at the initial and final points, respectively.
- Units of Potential Difference: The SI unit of potential difference is the volt (V), named after the Italian physicist Alessandro Volta. One volt is defined as one joule of energy per coulomb of charge (1 V = 1 J/C).
- Role of Potential Difference in Circuits: Potential difference plays a crucial role in electrical circuits. It provides the driving force for the flow of electric current. When a potential difference is applied across a conductor, such as a wire, it creates an electric field that causes the movement of charge carriers (usually electrons) through the conductor.
- Ohm’s Law: Ohm’s law relates potential difference, current, and resistance in a circuit. It states that the current flowing through a conductor is directly proportional to the potential difference across it, provided the temperature and other physical factors remain constant. Mathematically, Ohm’s law can be expressed as V = IR, where V is the potential difference, I is the current, and R is the resistance.
Understanding the concept of potential difference is essential for comprehending the behavior of electric circuits and various electrical devices. It forms the foundation for studying topics like electric current, electric power, and electrical measurements.
It’s important to note that this explanation provides a general understanding of the concept of potential difference. For a more comprehensive understanding and to excel in AIIMS entrance exams, it is recommended to refer to the specific textbooks and study materials recommended for the exam.
