AP EAMCET · PHYSICS · Current Electricity
In the given circuit, if the potential at point B is 24 V , the potential at point A is
- A \(-4.8 \mathrm{~V}\)
- B \(-2.4 \mathrm{~V}\)
- C \(-12 \mathrm{~V}\)
- D \(-14.4 \mathrm{~V}\)
Answer & Solution
Correct Answer
(B) \(-2.4 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
From the given circuit, \(\therefore \quad I=\frac{36-12}{3+2}=\frac{24}{5} A\) Again, by \(k \vee L\), \(\begin{aligned} & 24-12-3 \mathrm{I}=\mathrm{V} \\ & \Rightarrow \mathrm{~V}=12-3 \times \frac{24}{5}=-2.4 \mathrm{~V} \end{aligned}\)
