Say I have a circuit that looks like this: ...._______ B___|_|_|_|___ A The red and green lines are resistors. The black lines are wires. Assume a connection between any component line that is at a right angle to any other line, and a current source applied to points A and B. My question is this: Are the two green resistors in parallel, and thus, can I reduce them to a single resistor using (Ra*Rb)/(Ra+Rb)? If not, any suggestions on how to calculate the equivalent resistance of this entire circuit, between points A and B?
