Question

What limits the maximum current in an LCR circuit, just as friction limits the maximum amplitude of a swing?

विकल्प

• Resistance \[R\]

• Inductive reactance \[X_L\] alone

• Resonant angular frequency \[\omega_0\]

• Capacitive reactance \[X_C\] alone

Answer 1

Friction limits a swing's maximum amplitude, while resistance limits an LCR circuit's maximum current. At resonance, the maximum current amplitude is \[v_m/R\].
