Electricity and Magnetism
Electricity and magnetism are some of the most interesting parts of physics. While studying electric circuits, I learned that current flows when there is voltage, but resistance slows it down. In our experiments, we measured voltage, current, and resistance, which helped us confirm Ohm’s law: current is directly proportional to voltage and inversely proportional to resistance.
I also found magnetic fields fascinating, especially the fact that an electric current can create a magnetic field, and a magnetic field can induce an electric current. This made me realize the importance of electromagnetism in devices like motors, generators, and transformers. Now, whenever I see appliances at home, I think about how electricity and magnetism work together.
