Ideal voltmeter connected as shown reads
- A \(16 \mathrm{~V}\)
- B \(12 \mathrm{~V}\)
- C \(4 \mathrm{~V}\)
- D \(8 \mathrm{~V}\)
Answer & Solution
Correct Answer
(D) \(8 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
Here, \(6 \Omega\) and \(12 \Omega 2\) resistors are in parallel combination, so their equivalent resistance, \(R_{\mathrm{eq}}=\frac{6 \times 12}{6+12}=\frac{72}{18}=4 \Omega\) Now, \(R_{\mathrm{eq}}\) and \(4 \Omega\) are in series, so total resistance, \(R_{t}=4+4=8 \Omega\)…
