A practical Parallel resonant circuit has a coil in Parallel with a 0.14 μf capacitor. The coil has an inductance of 1 mH and a resistance of 10 ohms. The Q of the circuit is
Answer: Option
Explanation:
.
45.
An AC circuit has two branches in parallel. The current in one branch is 5 A. Then the current source
Answer: Option
Explanation:
5 A current may be (say) 3 + j 4A. The current in the other branch is x ± jy. The total current is (3 + x) + (4 ± y). This may be 5A or more or less.
