Class 12 Physics simulations · Alternating Current

Series RLC resonance

Sweep frequency and find the peak current.

Open the simulation

What to notice

At resonance, inductive and capacitive reactances cancel.

Key relation

f₀ = 1/(2π√LC)

Try this

Increase resistance and observe a broader, lower peak.

What you can change

• Inductance: 10 to 100 mH
• Capacitance: 10 to 100 µF
• Resistance: 5 to 50 Ω
• Driving frequency: 20 to 500 Hz
