1. The problem statement, all variables and given/known data If a 12 V supply is placed across AD, find effective resistance of whole circuit, current through resistor 3, and voltage reading on resistor 5 with polarity 2. Relevant equations Rn= Resistor number n I= current V= volts 3. The attempt at a solution I could not figure if the current would flow from c to b, or b to c, because there is no potential difference across it, and therefore could not solve the problem help please!!!
