AP EAMCET · PHYSICS · Current Electricity
In the circuit, the value of the current, I is
- A \(1 \mathrm{~A}\)
- B \(0.5 \mathrm{~A}\)
- C \(0.25 \mathrm{~A}\)
- D \(0.75 \mathrm{~A}\)
Answer & Solution
Correct Answer
(A) \(1 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
Cells are in series as positive terminal of one cell connected with the negative terminal of other cell. \(\begin{aligned} & \mathrm{Eq}=\mathrm{E}_1+\mathrm{E}_2 \\ & =12+6=18 \mathrm{~V} \\ & \mathrm{req}=\mathrm{r}_1+\mathrm{r}_2 \\ & =6+3 \\ & =9 \Omega\end{aligned}\) Now,…
