The Nucleus contains Protons and Neutrons.
The Neutrons does not have a charge.
The Protons are positively charge.
Hence the charge on the Nucleus, would be the charge of the proton, which is positive. 
Hence Nucleus is Positively Charged.
        
             
        
        
        
If she has a choice and the wiring details are stated on the packaging, 
then Janelle should look for lights that are wired in parallel within the 
string, and she should avoid lights that are wired in series within the string.  
If a single light in a parallel string fails, then only that one goes out.  
The rest of the lights in the string continue to shimmer and glimmer.
If a single light in a series string fails, then ALL of the lights in that string 
go out, and it's a substantial engineering challenge to determine which light 
actually failed.
