A student connects a cell of emf `epsilon_(2)` and internal resistance `r_(2)`, with a cell of emf `epsilon_(1)` such that their combinationhas a net internal resistance less then `r_(1)`. This combination in the connected across a resistance `R`. Draw a circuit of the 'set up' and obtain an external for the current flowing through the resistance `R`
