SUMMARY
Graphene is significantly lighter than copper while offering superior conductivity. A copper busbar weighing 7 kg with a resistance of 2 micro-ohms can carry substantial current, whereas a graphene conductor, potentially weighing less than 1 kg, can achieve similar current-carrying capabilities. The discussion emphasizes the importance of calculating the resistivity-to-weight ratio to understand the advantages of graphene over copper. Additionally, cost considerations play a crucial role in the choice of materials for busbars.
