Class 12 Physics simulations · Alternating Current

AC generator

Rotate a coil and track the alternating voltage it produces.

Open the simulation

What to notice

Voltage changes sign every half cycle; the effective RMS voltage is smaller than the peak.

Key relation

V(t) = V₀ sin(2πft)

Try this

Double the frequency. How does the period change?

What you can change

• Peak voltage: 10 to 120 V
• Frequency: 0.2 to 2 Hz
