Problem to solve

Given the circuit pictured here, solve for IR1, IR2, IR3 and IR4 as well as IT and RT.  be sure to label your answers.  

 

Memory

redraw the ladder diagram to add memory.  indicate where the connections need to me on the magnetic motor starter so that memory will work as well as the overload relay.

 

Figure it out

Solve for Rt, It, IR 1, IR 2, IR 3, and IR 4.  Remember parallel circuit rules are different than series circuit rules.

 

Compare this with the prior picture

What's inside the green circle ?

Hmmm....
