I am working through some notes which use the following metric diag(1,-1,-1,-1).

They give the 4-potential as ( A

^{μ}) = ( V/c ,

**A**) where V is the scalar potential and

**A**is the vector potential. This should mean in components A

^{0}= V/c and A

^{1}= A

_{1}and so on but with the metric given shouldn't A

^{1}= - A

_{1}?

Thanks
