Circuit Formulas

Ohm's Law
I = V ÷ R
Current equals Voltage divided by Resistance.
Electric Power
P = V × I
Power = Voltage × Current (Watts).
Power Dissipation
P = I² × R
Heat power in resistor.
Energy Consumed
E = P × t
Energy (Joules) = Power × Time.

How to Use

  • Adjust Voltage & Resistance using sliders or presets.
  • Click Turn ON/OFF (top bar) to energize the circuit.
  • Watch electrons flow & bulb brightness change with power.
  • Real-time current, power, energy, and time update automatically.
  • Reset clears accumulated energy and stops simulation.
  • Responsive design works on phones, tablets, laptops, and desktops.
