Grid Balancing

Keep supply = demand to maintain 50 Hz frequency. Too much supply raises frequency, too little drops it. Balance renewable (cheap) and fossil (expensive) sources to meet demand at lowest cost.

Electrical Circuit Simulator — AC & DC

Electrical engineering starts with understanding how charge flows through circuits composed of passive components and sources. This simulator supports both DC analysis — using Kirchhoff's laws — and AC analysis with phasors and impedance for sinusoidal steady-state circuits. Drag-and-drop components and instant measurements make it ideal for verifying Ohm's law, superposition, and resonance concepts.

What you can do in this simulation

Place resistors, capacitors, inductors, voltage sources, and current sources
Switch between DC and AC (sinusoidal) analysis modes
Measure node voltages and branch currents with virtual probes
Observe impedance and phase angle in AC circuits as frequency changes
Identify resonance in RLC circuits by sweeping input frequency

Concepts covered

Ohm's law · impedance · phasor · Kirchhoff's laws · resonance · AC circuits
