The voltage and the current between A and B points shown in the circuit are ______. (a) 24 V, 12 A (b) 24 V, 4 A (c) 18 V, 12 A (d) 27 V, 4 A

Answer: (b). Four identical branches (27 V, 3 Ω) lie in parallel between A and B; the 14 V + 13 V branch is also 27 V. Equivalent source: E = 27 V, r = 3/4 = 0.75 Ω Load between A and B: 3 + 3 = 6 Ω I = (27)/(6 + 0.75) = 4 A, V = 4 × 6 = 24 V So the answer is (b) 24 V, 4 A.

Kirchhoff's Laws & Measuring Instruments

The voltage and the current between $A$ and $B$ points shown in the circuit are ______.

Show answer and solution

Answer: (b)

Four identical branches (27 V, 3 Ω) lie in parallel between A and B; the 14 V + 13 V branch is also 27 V.
Equivalent source: $E = 27\text{ V}$ , $r = \frac{3}{4} = 0.75\ \Omega$
Load between A and B: $3 + 3 = 6\ \Omega$
$I = \frac{27}{6 + 0.75} = 4\text{ A}$ , $V = 4 \times 6 = 24\text{ V}$
So the answer is (b) 24 V, 4 A.
