Class 12 Physics simulations · Electrostatic Potential and Capacitance

Equipotentials around a point charge

Move a probe around a charge and connect electric potential with field direction.

Open the simulation

What to notice

Moving around one circular equipotential costs no electrostatic work. Moving radially changes potential.

Key relation

V = kQ/r; E = k|Q|/r²

Try this

Keep radius fixed and change the probe angle through a complete circle.

What you can change

• Source charge: -5 to 5 nC
• Probe radius: 0.3 to 2 m
• Probe angle: 0 to 360 °
