A 9–volt battery is connected to four resistors to form a simple circuit as shown below.
What would be the current at point E in the circuit?
(A) 2 amp
(B) 4 amp
(C) 5 amp
(D) 7 amp
(E) 9 amp
The correct option is: (A) 2 amp
Explanation:
ACD = 9 Ω, ABD = 9 Ω so the total resistance is 4.5 Ω making the total current ε/R = 2 A.
