1. The problem statement, all variables and given/known data Number 8 2. Relevant equations V = IR 3. The attempt at a solution The points above the 3 horizontal lines represent grounded areas. They have zero electric potential there. How does the circuit work when it is grounded midway? I found the total resistance to be 13 2/3 Since V = IR 24 = I * 13 2/3 I = 1.75 Why didn't this work?
