How does the terminal velocity of the metal ball in cm s-1 moving vertically downwards through glycerin depends on the radius (in cm) of the metal balls, determined by measuring the time taken for the ball to fall?
This IB Diploma internal assessment investigates the process of converting alternating current (AC) to direct current (DC) in electronic devices such as laptops, iPads, and mobile phones. The student's curiosity about the role and components of chargers led to exploring topics such as diodes, capacitors, and dielectrics. The project aims to understand the conversion process, explore methods of AC-DC conversion, and examine the possibility of varying the conversion rate. The research question focuses on the concept of ripple factor and its implications in AC-DC conversion.
Determination of a relationship between Co-efficient of Linear Thermal Expansion of Solid with respect to the Resistivity of the material.
This IB Diploma internal assessment explores the relationship between thermal expansion of solids and its effect on current flow in conductors. The student's curiosity was sparked while observing gaps at the junction of railway tracks and relating it to the concept of solid expansion. The investigation aims to investigate how the expansion of solid materials due to temperature changes can impact the microscopic properties that control the flow of electric charge, and whether it has implications for electricity and conductors.
