two cells of emf 10v and 2 v and internal resistance 10 n 5 respectively are connected in parallel.find effective voltage across R which is placed parallel to both
Please find below the solution to the asked query:
Given situation is drawn in the following diagram.
So, the circuit can be simplified to a state, where a single cell of emf and a single internal resistance can be placed between A and B. Here, the question is to calculate VAB.
So, from effective resistance formula,
from effective emf formula,
