Our modern society consumes electrical energy daily, yet we rarely stop to consider the science behind them. Electromagnetic induction is a phenomenon with various practical applications in our daily life, and it is used…

The power we use in our residential areas and office buildings typically utilises an alternating current (AC) due to its efficiency. However, there may be instances where a device requires the use of a…

Circuits consisting of just one battery and a resistor are very easy to study, but they are not often used in practical applications. We typically see circuits where there are more than two components…

Electricity is used daily to operate your cell phones, power transports, and keep your home appliances such as the refrigerator running. If you are attending physics tuition, you would know that the concept of…

Electromagnetism is a branch of study concerned with the interactions between electrically charged particles, namely, due to electromagnetic force. Electromagnetic force is carried along electric fields and magnetic fields. For example, when an electric…

When you rub a balloon on your head, electrons are moved from your hair to the surface of the balloon. The electrons will stick to the side of the balloon where it was rubbed…

Polarisation is a phenomenon caused due to the wave nature of electromagnetic radiation. It is an important property of light that affects even those optical systems that do not specifically measure it. The polarisation…

What does a guitar, swing, or a rocking chair have in common? They all oscillate – in a way, they move back and forth between two points. Oscillations can create waves. For example, a…

In most cases in physics, when people discuss about the theory of superposition, they are talking about waves. Example of waves includes light, sound, water, and earthquake waves. We all know that two objects…
