AP EAMCET · PHYSICS · Alternating Current
In the circuit shown in the figure, neglecting the source resistance, the voltmeter and ammeter readings respectively are
- A \(0 \mathrm{~V}, 8 \mathrm{~A}\)
- B \(150 \mathrm{~V}, 3 \mathrm{~A}\)
- C \(150 \mathrm{~V}, 6 \mathrm{~A}\)
- D \(0 \mathrm{~V}, 3 \mathrm{~A}\)
Answer & Solution
Correct Answer
(A) \(0 \mathrm{~V}, 8 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{R}=30 \Omega, \mathrm{X}_{\mathrm{L}}=25 \Omega, \mathrm{X}_{\mathrm{C}}=25 \Omega\) \(\therefore \quad \mathrm{Z}=\sqrt{\left(\mathrm{X}_{\mathrm{L}}-\mathrm{X}_{\mathrm{C}}\right)^2+\mathrm{R}^2}=30 \Omega\) \(\therefore\) Reading of ammeter,…
