Case Studies

Electric short circuit case

This case study explores how an electric short circuit occurs in household wiring and why safety devices like fuses and circuit breakers are essential. Through a real-life scenario in an Indian home, students analyze the causes, risks, and preventive measures related to excessive current flow.

Magnetic effects in electric motor

This case study explains how electric motors work using the magnetic effects of electric current. Through real-life examples such as electric fans and water pumps commonly used in Indian households, students explore how current-carrying conductors interact with magnetic fields to produce motion.

Photosynthesis in greenhouse

This case study explores how greenhouse farming improves photosynthesis by controlling factors such as light, temperature, humidity, and carbon dioxide. Through a real-life example of modern Indian agriculture, students understand how environmental conditions influence plant growth and crop yield.

Refraction in spectacles

This case study explains how refraction in spectacle lenses helps correct common vision defects such as myopia and hypermetropia. Through a real-life scenario of students using spectacles, it connects the physics concept of refraction with the functioning of concave and convex lenses in everyday life.

Dialysis machine functioning

This case study explains how a dialysis machine works when kidneys fail to filter blood properly. Using a real-life hospital scenario, students learn how diffusion through a semi-permeable membrane removes waste products such as urea from blood, demonstrating the role of excretion and artificial kidney technology in human health.

Life processes in marathon runner

This case study explores how life processes such as respiration, circulation, and energy release support a marathon runner during a long-distance race. Through a real-life sports scenario, students understand how oxygen supply, glucose metabolism, and muscle activity help the body maintain energy and endurance during intense physical activity.
