School stories

Savremena’s Physics teacher, Ms Ana Vlašić, made sure that Year 11 students never forget the practical lesson that was held on Tuesday, 19 November. With the help of their teacher they created their own electric circuits.

Ohm’s law

Ohm’s law states that the potential difference across a resistor is equal to the product of its resistance and the current going through. Ohm’s law is used to calculate electrical values so that we can design circuits and use electricity in a useful manner.

Electrical circuits – DIY

After learning about currents, resistors and resistor networks, the students created their own electric circuits. The resistors and batteries were connected based on assigned sketches. The students successfully connected up to three resistors in parallel and series networks. Afterwards, batteries were attached, and the potential differences across each of the resistors were measured. The potential differences that formed across resistors were shown to follow the rules of Ohm’s law. The students noticed that the two types of resistor networks follow certain rules for currents and potential differences. For example, the series network of resistors distributes the potential differences based on the resistances.

The students got a better understanding of why the series network is also called a ‘potential divider’, while the parallel network is a ‘current divider’.

International School Savremena offers its students an opportunity to apply their knowledge practically even in an abstract scientific context.
