Class 12 Physics simulations · Alternating Current

Energy exchange in an LC circuit

Watch a charged capacitor and an inductor exchange electric and magnetic energy.

Open the simulation

What to notice

At maximum current, all stored energy is magnetic.

Key relation

ω = 1/√LC; UE + UB = constant

Try this

Increase inductance and compare the oscillation period.

What you can change

• Inductance: 10 to 200 mH
• Capacitance: 10 to 200 µF
• Initial voltage: 1 to 20 V
