Q148 / 160 · TS EAMCET 2020 (11 Sep Shift 1) · Physics
The total current supplied to the following circuit by the battery is


- Correct answerA$4 \mathrm{~A}$
- B$2 \mathrm{~A}$
- C$1 \mathrm{~A}$
- D$6 \mathrm{~A}$
Solution
The given circuit diagram is shown below

Redrawing the above circuit diagram as
Equivalent resistance of the circuit is given as $R=[(6 \| 2)+1.5] \| 3$ $=\left[\frac{6 \times 2}{6+2}+1.5\right]\|3=3\| 3=\frac{3 \times 3}{3+3}=1.5 \Omega$ $\therefore$ Total current supplied to the circuit by the battery, $I=\frac{V}{R}=\frac{6}{1.5}=4 \mathrm{~A}$

Redrawing the above circuit diagram as

Equivalent resistance of the circuit is given as $R=[(6 \| 2)+1.5] \| 3$ $=\left[\frac{6 \times 2}{6+2}+1.5\right]\|3=3\| 3=\frac{3 \times 3}{3+3}=1.5 \Omega$ $\therefore$ Total current supplied to the circuit by the battery, $I=\frac{V}{R}=\frac{6}{1.5}=4 \mathrm{~A}$
Hence, the correct answer is option: 'A'.
