Two cells are connected in opposition as shown. Cell E 1 is of 8 V emf and 2 Ω internal resistance; the cell E 2 is of 2 V emf and 4 Ω internal resistance. The terminal potential difference of cell E 2 is ______ V .

Correct answer

0

Step-by-step solution

Current in circuit, I = 8 - 2 2 + 4 = 6 6 = 1 A Applying Kirchhoff's law from C to B , V C - 2 - 4 × 1 = V B ⇒ V C - V B = 6 V
