Physics · Class 12 · CBSE — Current Electricity
Two cells of emf 2 V and 3 V, and internal resistance \(1 \Omega\) and \(2 \Omega\) , respectively are connected in parallel. The effective emf and internal resistance of the combination cell are respectively:
- \(3 {~V}, 1 \Omega\)
- \(5 {~V}, 3 \Omega\)
- \(\frac{7}{3} {~V}, \frac{2}{3} \Omega\)
- \(\frac{6}{5} {~V}, \frac{2}{3} \Omega\)
Answer
(C) 7 3 ~V , 2 3
