Ohm's Law Circuit Simulator

Interactive visualization of electrical circuits demonstrating Ohm's Law: V = I × R

Circuit Controls

Voltage (V): 1.50 V
Resistance (Ω): 10.0 Ω

Circuit Status

Circuit Open - No Current Flow

Ohm's Law Display

V = I × R
1.50 = 0.00 × 10.0

Ohm's Law: Voltage (V) = Current (I) × Resistance (R)

When the circuit is closed, current flows according to this formula.

Circuit Components

Power Source (V)
Provides voltage to push electrons
Switch
Controls current flow
Resistor (R)
Opposes current flow
Light Bulb
Visual indicator of current

How It Works

  • Close the circuit by toggling the switch to see current flow
  • Adjust voltage (V) - increasing voltage increases current
  • Adjust resistance (R) - increasing resistance decreases current
  • Watch how Ohm's Law (V = I × R) is always true
  • Notice that current only flows when the circuit is complete (closed)
  • Click directly on the switch in the diagram to open/close the circuit
