JEE Mains · Physics · STD 12 -7. Alternating current
Given below are two statements: Statement \(I\): An \(AC\) circuit undergoes electrical resonance if it contains either a capacitor or an inductor. Statement \(II\): An \(AC\) circuit containing a pure capacitor or a pure inductor consumes high power due to its non-zero power factor. In the light of above statements, choose the correct answer from the options given below
- A Both Statement \(I\) and Statement \(II\) are false
- B Statement \(I\) is true but Statement \(II\) is false
- C Both Statement \(I\) and Statement \(II\) are true
- D Statement I is false but Statement \(II\) is true
Answer & Solution
Correct Answer
(A) Both Statement \(I\) and Statement \(II\) are false
Step-by-step Solution
Detailed explanation
For resonance, \(\phi=0\), hence both inductor and capacitor must be present. Also power factor is zero for pure inductor or pure capacitor hence both the component consume zero average power.
