In the circuit above, the emf'* and the resistances have the values shown. The current I in the circuit is 2 amperes.
The potential difference between points X and Y is
(A) 1.2 V
(B) 6.0 V
(C) 8.4 V
(D) 10.8 V
(E) 12.2 V
The correct option is: (C) 8.4 V
Explanation:
Summing the potential differences: – 6 V – (2 A)(0.2 Ω) – (2A)(1 Ω) = – 8.4 V
