Current Question (ID: 20224)

Question:
$\text{In the given circuit, an } 8\ \text{V battery powers a network of resistors. The current } i_1 \text{ flows from point } A \text{ to point } C \text{ through the resistor network. The value of } i_1 \text{ is:}$
Options:
  • 1. $2\ \text{A}$
  • 2. $1\ \text{A}$
  • 3. $5\ \text{A}$
  • 4. $4\ \text{A}$
Solution:
$\text{Hint: } V = IR$ $\text{Step: Find the current flowing from } A \text{ to } C. \text{ Resolving the circuit, we get;} \newline ABCD \text{ represents a balanced Wheatstone bridge, so } V_B = V_D. \text{ Thus, no current passes from } B \text{ to } D. \newline \text{The voltage across } AC = 8\ \text{V} \newline \text{The current } i_1 \text{ flowing through } AC \text{ is given by;} \newline \Rightarrow i_1 = \frac{V_{AC}}{R_{AC}} = \frac{8}{4+4} = 1\ \text{A} \newline \text{Hence, option (2) is the correct answer.}$
