Can anyone let me know where i can find all the formula regarding power circuit calculation?Especially those line voltages,phase current,line current,load currents,load voltages,power per phase and total power.

And is it true that line current = phase current?Does that apply to anything regardless delta or star?Thanks in advance.I need this for my exam.
