The reading in the ideal voltmeter \((V)\) shown in the given circuit diagram is _______.
- A \(5 \mathrm{~V}\)
- B \(10 \mathrm{~V}\)
- C \(0 \mathrm{~V}\)
- D \(3 \mathrm{~V}\)
Answer & Solution
Correct Answer
(C) \(0 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
\({i}=\frac{\mathrm{E}_{\text {eq }}}{\mathrm{r}_{\text {eq }}}=\frac{8 \times 5}{8 \times 0.2}\) \(I=25 \mathrm{~A}\) \(V=E-1 \mathrm{r}\) \(=5-0.2 \times 25\) \(=0\)
