AP EAMCET · PHYSICS · Alternating Current
\(\frac{50}{\pi} \mu \mathrm{F}\) capacitor is connected to a \(250 \mathrm{~V}, 50 \mathrm{~Hz}\)
AC supply. Then the rms current of the circuit is
- A \(1.25 \mathrm{~A}\)
- B \(4.9 \mathrm{~A}\)
- C \(5 \mathrm{~A}\)
- D \(6 \mathrm{~A}\)
Answer & Solution
Correct Answer
(A) \(1.25 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
Given, \(C=\frac{50}{\pi} \mu \mathrm{F}=\frac{50}{\pi} \times 10^{-6} \mathrm{~F}\) Source voltage, \[ \begin{aligned} & V=250 \mathrm{~V} \\ & f=50 \mathrm{~Hz} \end{aligned} \] Capacitive reactance,…
