At its core, electricity is the flow of electrons through a conductor, and this flow can be harnessed to do work. Most electrical appliances operate on the principle of Ohm's Law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. This relationship can be summarized in the formula: V I × R.

Additionally, appliances are designed with various components, such as resistors, capacitors, and inductors, which manipulate electrical energy to perform specific tasks. For instance, a toaster uses resistors to convert electrical energy into heat, toasting your bread to perfection. The efficiency of these appliances is often measured in terms of their energy consumption, which is why looking for energy-efficient models can save you money on your electricity bill.

Refrigerators utilize thermodynamic principles to maintain low temperatures, making them an essential part of modern life. At first glance, these appliances might seem simple, but they operate based on the laws of thermodynamics, specifically the second law, which states that heat naturally flows from hot to cold. Refrigerators counteract this natural flow by using a refrigeration cycle that involves a refrigerant, which absorbs heat from inside the fridge and releases it outside. This process can be broken down into four main stages: compression, condensation, expansion, and evaporation.

During compression, the refrigerant gas is compressed, raising its temperature and pressure. Next, in the condensation phase, the hot gas passes through coils where it releases heat and turns into a liquid. The refrigerant then expands, dropping in pressure and temperature, and finally, it evaporates inside the fridge, absorbing heat from the interior. This continuous cycle ensures that your food stays fresh and cool.
