Electric field
The electric field is a fundamental concept in physics that describes the influence of electric charges on other charges and objects in their vicinity. It is a vector field, meaning it has both magnitude and direction.
Electric fields are created by electric charges. When a charged object, such as a proton or an electron, is present, it creates an electric field in the space around it. The electric field exerts a force on other charged objects placed within its influence.
The electric field at a particular point in space is defined as the force per unit positive charge experienced by a test charge placed at that point. Mathematically, the electric field (E) at a point is given by the equation:
E = F/q
where E is the electric field, F is the force experienced by the test charge, and q is the magnitude of the test charge. The electric field is measured in units of volts per meter (V/m).
The electric field lines are used to visualize the electric field. Electric field lines show the direction of the field at different points and provide information about the relative strength of the field. The field lines originate from positive charges and terminate on negative charges. They never intersect each other, and the density of the lines indicates the strength of the electric field.
The electric field obeys the principle of superposition, which means that the total electric field at a point due to multiple charges is the vector sum of the electric fields produced by each individual charge.
The electric field plays a crucial role in various phenomena and applications, including:
- Electric force: The electric field determines the force experienced by a charged object placed within it. The force is given by the equation F = qE, where F is the force, q is the charge, and E is the electric field.
- Capacitors: The electric field is used to store electrical energy in capacitors by creating a potential difference between two conductive plates.
- Electric circuits: The electric field facilitates the flow of electric current in conductors and components of electrical circuits.
- Electrical interactions: The electric field is responsible for the attraction or repulsion between charged objects, influencing their behavior and interactions.
Understanding the electric field is essential in many areas of physics, including electromagnetism, electronics, and electrical engineering. It provides the foundation for comprehending various phenomena and applications related to electric charges and their interactions.

Case Study on AIIMS-SYLLABUS Physics syllabus Electric field
Certainly! Let’s consider a case study on the electric field.
Case Study: Electric Field in Medical Imaging
Medical imaging techniques play a crucial role in diagnosing and treating various medical conditions. One such technique that utilizes the concept of electric fields is Electroencephalography (EEG).
EEG is a non-invasive medical imaging technique used to measure the electrical activity of the brain. It helps in diagnosing and monitoring conditions such as epilepsy, sleep disorders, brain tumors, and neurological disorders. The fundamental principle behind EEG is the detection and measurement of electric fields generated by the brain’s neurons.
In EEG, electrodes are placed on the scalp of the patient to detect the electrical signals produced by the brain. These signals, known as brainwaves, are very weak and require sensitive equipment to detect and record them accurately. The electrodes are connected to an amplifier that amplifies the signals for further analysis.
The electric field generated by the brain’s electrical activity is responsible for the propagation of the electrical signals from the neurons to the electrodes on the scalp. The electric field lines originating from active neurons create an electric potential gradient, allowing the electrical signals to flow through the conductive medium of the brain, cerebrospinal fluid, skull, and scalp.
The electrodes in EEG measure the potential difference between pairs of electrodes placed on the scalp. By analyzing the variations in the recorded electrical signals, neurologists and medical professionals can study the brain’s electrical activity patterns and identify abnormalities or specific patterns associated with different neurological conditions.
Understanding the electric field in EEG is crucial for accurate interpretation of the recorded signals. Factors such as electrode placement, conductive medium, and electrical properties of the tissues affect the electric field distribution and signal characteristics. Signal processing techniques are employed to filter out noise and extract meaningful information from the recorded signals.
The study of the electric field in EEG involves understanding the principles of electric potential, electric field lines, and the behavior of electric fields in conductive media. It also requires knowledge of signal processing techniques to analyze and interpret the recorded electrical signals.
The application of the electric field in medical imaging extends beyond EEG. Other imaging techniques, such as electrocardiography (ECG) and electromyography (EMG), also rely on the detection and measurement of electric fields generated by the heart and muscles, respectively.
In conclusion, the understanding and analysis of the electric field play a vital role in medical imaging techniques like EEG. By harnessing the principles of electric fields, medical professionals can non-invasively study and diagnose various neurological conditions, leading to better patient care and treatment.
