Electrical power transmission through cables plays a crucial role in delivering electricity to our homes, businesses, and industries. Cables are essential components of the electrical grid, serving as conduits for the flow of energy from power plants to end-users.The power transmitted through a cable is determined by the voltage and current it carries, as described by the fundamental power formula, P = VI. However, it's important to consider power losses due to the inherent resistance in the cable material. These losses, as calculated using the formula P_loss = I^2R, can result in a decrease in the delivered power. Engineers and electricians carefully select and design cables to minimize such losses and ensure efficient energy transmission, contributing to the reliability and sustainability of our electrical infrastructure.
