Question) Study the circuit diagram and answer the following questions.
(i) the potential difference across 2 ohms
 (ii) the potential difference across the internal resistance of the cell
(iii) the potential difference across R ohms and 4 ohms
(iv) the value of R

Dear Student,
                     1)  potential difference across 2 ohms=0.6×2=1.2V2) potential difference across the internal resistance of the cell=0.6×1=.6V3)the potential difference across R ohms and 4 ohms=3.6-1.2-.6=1.8V4) R=1.80.6-1.84=12ohm
