Class 12 Physics simulations · Alternating Current

Reactance versus frequency

Sweep the frequency and compare inductive and capacitive reactance.

Open the simulation

What to notice

Inductors block high frequencies; capacitors block low frequencies.

Key relation

X_L = 2πfL; X_C = 1/(2πfC)

Try this

Find the frequency where the two reactances are equal.

What you can change

• Inductance: 1 to 100 mH
• Capacitance: 1 to 100 µF
• Frequency: 10 to 500 Hz
