Metallic bonds can help create electric currents, but there are some problems that get in the way:

1. Free Electron Movement:

   • Electrons in metallic bonds can move around freely, which helps with conductivity. But when there are impurities or defects in the metal, this flow can get interrupted.

2. Resistance:

   • Metals have something called resistance. This means that some energy gets lost as heat. When the temperature goes up, resistance can increase, making it even harder for the current to flow.

3. Structural Limitations:

   • The way atoms are arranged in a metal can affect how well it conducts electricity. Over time, if the metal gets damaged or wears down, its ability to conduct electricity can suffer.

To fix these problems, we can work on making the metal purer. Also, using special mixtures of metals, called alloys, can help improve their performance for specific electrical uses.
