Electro Magnetic Induction And Alternating Currents Question 42
Question: If an $ 8,\Omega $ resistance and $ 6,\Omega $ reactance are present in an ac series circuit then the impedance of the circuit will be [MP PMT 2003]
Options:
A) 20 ohm
B) 5 ohm
C) 10 ohm
D) $ 14\sqrt{2} $ ohm
Show Answer
Answer:
Correct Answer: C
Solution:
Impedance $ Z=\sqrt{R^{2}+X^{2}}=\sqrt{{{(8)}^{2}}+{{(6)}^{2}}}=10\Omega $
