Problem

In the circuit shown in the figure each of cell has emf

\epsilon

= 2.25 V and all the cells are ideal. The value of each resistance

R = 2\Omega

. The magnitude of potential difference (in V) between the points M and N is ![A complex electrical circuit diagram. It features a horizontal top wire and a horizontal bottom wire. Five identical cells, each with emf ε, are connected in series along the top wire. Five identical cells, each with emf ε, are connected in series along the bottom wire. Between the top and bottom wires, there are five vertical branches. Each branch contains two resistors, each labeled R, connected in series. The top resistor in each branch is connected to the top wire, and the bottom resistor is connected to the bottom wire. The branches are connected to the top wire at points that are ε apart, and to the bottom wire at points that are ε apart. The leftmost connection point on the top wire is labeled R, and the rightmost connection point on the bottom wire is labeled M. The connection point on the top wire between the second and third branches is labeled N.](https://storage.googleapis.com/diraq-contents/homework-question-parsing/marker/20260117T131741Z/252505eed90444a1aca9a5af4e1cd7dd/e84c7434834958f49141d04130194231_img.jpg)
