Transformer
Here are some key points about transformers:
- Basic Structure: A transformer consists of two coils of wire, called primary and secondary windings, wound around a common iron core. The primary winding is connected to an AC power source, while the secondary winding is connected to the load.
- Principle of Operation: When an alternating current (AC) flows through the primary winding, it generates a magnetic field in the iron core. This changing magnetic field induces an alternating current in the secondary winding, allowing the energy to be transferred from the primary to the secondary circuit.
- Turns Ratio: The turns ratio of a transformer is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. It determines the voltage ratio between the primary and secondary circuits.
- Voltage and Current Transformation: Transformers can step up or step down the voltage depending on the turns ratio. A step-up transformer increases the voltage, while a step-down transformer decreases the voltage. At the same time, the current is inversely proportional to the turns ratio, i.e., if the voltage is stepped up, the current is stepped down, and vice versa.
- Efficiency: Transformers are highly efficient devices, with efficiencies often exceeding 95%. However, there are losses such as resistive losses in the windings and magnetic core losses, which can reduce the overall efficiency.
- Applications: Transformers are used in various electrical systems and devices, including power distribution networks, electrical appliances, electronic devices, and even in power adapters for charging electronic devices.

Transformers in AIIMS Physics Syllabus
Introduction: In the AIIMS Physics syllabus, the topic of transformers plays a significant role in understanding the principles of electromagnetism and electrical circuits. Let’s explore a case study that focuses on the application of transformers in medical equipment used in AIIMS hospitals.
Case Study Scenario: AIIMS Hospital recently acquired a state-of-the-art MRI machine, which requires a stable and regulated power supply. However, the hospital’s power grid fluctuates frequently, making it necessary to implement a robust power conditioning system. The hospital’s electrical department decides to use transformers as a crucial component of the power conditioning setup.
Objective: The objective of this case study is to analyze the implementation of transformers in the power conditioning system of the AIIMS Hospital’s MRI machine and understand their role in maintaining a stable power supply.
Implementation and Analysis:
- Voltage Regulation: The primary purpose of the transformers in this setup is to regulate the voltage supplied to the MRI machine. The transformers step down the high-voltage electricity from the power grid to the desired level required by the MRI machine, ensuring a consistent and safe voltage supply.
- Isolation: Transformers also provide electrical isolation between the power grid and the MRI machine. This isolation protects the sensitive electronic components of the machine from power grid disturbances, such as voltage spikes and electrical noise.
- Efficiency and Losses: The transformers used in the power conditioning system are carefully selected to ensure high efficiency and minimize power losses. This helps optimize the energy usage and reduces the heat dissipation within the transformers.
- Power Quality: Transformers contribute to improving the power quality supplied to the MRI machine. They help mitigate issues such as voltage sags, harmonics, and transient disturbances, ensuring a stable and reliable power supply. This, in turn, enhances the performance and accuracy of the MRI machine.
- Safety Measures: The transformers used in the power conditioning system incorporate safety features like protective circuits, insulation, and grounding. These measures protect the machine, medical staff, and patients from electrical hazards, enhancing overall safety in the hospital environment.
Conclusion: Transformers play a crucial role in maintaining a stable and regulated power supply in medical equipment such as MRI machines. In the case of AIIMS Hospital, the implementation of transformers in the power conditioning system ensures a reliable and high-quality power supply to the MRI machine. This contributes to the accurate diagnosis and treatment of patients, providing a safe and efficient healthcare environment.
Please note that this case study is a fictional scenario created to demonstrate the application of transformers in the context of AIIMS Physics syllabus. The actual implementation of transformers in medical equipment may vary, and specific details should be obtained from relevant sources or professionals in the field.
