Q2.What was Nikola Tesla really good at?

2/4

Q3.Sort the statements below into the advantages and disadvantages of alternating current electricity,
A well made transformer is nearly 100% efficient.
High potential differences can be used, so lower currents will be needed over long distances, increasing the efficiency of the system.
Alternating current systems result in cheaper energy bills.
Transformers allow the potential difference to be increased and decreased.
Transformers are heavy and expensive to build.
