Circuit Calculator - The Essential Tool for Circuit Solutions:

Solve circuit problems effortlessly! Circuit Calculator is the go-to app for students, engineers, and electronics enthusiasts. Quickly build, simulate, and solve linear AC and DC circuits - ideal for study, verification, or practical use.

Build, Solve & Review Results:

• Create schematics by dragging, rotating, and snapping components • Tap solve to compute steady-state voltages and currents • Follow DC current flow with real-time animations • Zoom and pan around to review results directly on the schematic • Tap detailed analysis to also compute power values

Perfect for Learning & Quick Verification:

Whether you're checking your homework or confirming a design, Circuit Calculator supports both rectangular and polar notation - just like textbook problems. It focuses on steady-state behaviour in linear circuits, making it ideal for academic and professional use.

Other Key Features:

• Interactive user guide • Pre-built example circuits • Supports DC and sinusoidal AC circuits • Computes Thévenin and Norton equivalents • Save to iCloud for access across devices • Export/share circuits or PDF snapshots • Import circuits from others • Undo/redo and copy/paste support

Available Components:

• Independent Ideal Current Sources • Independent Ideal Voltage Sources • Current-Controlled Current Sources • Current-Controlled Voltage Sources • Voltage-Controlled Current Sources • Voltage-Controlled Voltage Sources • Resistors, Capacitors & Inductors • Mutually Coupled Inductors (AC only) • Impedances (AC only) • Diodes (DC only)
