Electro Magnetic Induction And Alternating Currents Question 166
Question: In an ac circuit an alternating voltage e=200 $ \sqrt{2},\sin ,100,t $ volts is connected to a capacitor of capacity $ 1,\mu F $ . The r.m.s. value of the current in the circuit is
Options:
A) 10 mA
B) 100 mA
C) 200 mA
D) 20 mA
Show Answer
Answer:
Correct Answer: D
Solution:
-
$ V_{rms}=\frac{200\sqrt{2}}{\sqrt{2}}=200V $
$ I_{rms}=\frac{V_{rms}}{X_{C}}=\frac{1}{100\times {{10}^{-6}}}=2\times {{10}^{-2}}=20m,A $
