Series Parallel Circuit Solver is the easy way to build any series, parallel or mixed circuit and get the answer instantly. Draw your circuit by tapping, see the equivalent resistance, capacitance or inductance live, and follow every step of the solution. A complete series parallel calculator, parallel resistor calculator and resistor color code tool for students, hobbyists and technicians. BUILD ANY CIRCUIT BY TAPPING • Add resistors, capacitors or inductors in series or in parallel with one tap • Group parts to make mixed series-parallel circuits of any size • Copy, delete, undo and redo, and zoom in on big circuits • The answer updates live while you build • Choose the zigzag (US) or box (IEC) resistor symbol DC AND AC CIRCUITS • DC: solve resistors, capacitors or inductors in series and parallel • AC: mix R, L and C in one circuit at any frequency • Impedance in polar and rectangular form, with the phase angle • A true RLC impedance calculator for AC homework VOLTAGE, CURRENT AND POWER OF EVERY PART • Add a voltage or current source to your circuit • Get a clear results table: voltage, current and power for each resistor • In AC circuits, also see real, reactive and apparent power and the power factor (leading or lagging) • Show the voltages right on the circuit drawing STEP-BY-STEP SOLUTION • See how the circuit is solved, one step at a time • Every step shows the formula and the numbers used • Perfect for homework, lab reports and exam practice • Learn how equivalent resistance is really found, not just the final number READY-MADE TEMPLATES Start fast with a series chain, parallel bank, mixed circuit, ladder, two banks, lab circuit, capacitor bank or speaker crossover. QUICK SERIES & PARALLEL CALCULATOR • Type values on a circuit keypad, for example 10k ‖ 10k + 4.7k • Works for resistors, capacitors and inductors • Live total, drawing and steps as you type • The fastest parallel resistor calculator for quick checks RESISTOR COLOR CODE CALCULATOR • Bands to value: 3, 4, 5 and 6 band resistors, with tolerance and temperature coefficient • Value to bands: enter any value and see its color bands • Nearest standard value from E6 to E192 RESISTOR COMBINATION FINDER • Need a value you don't have? Make it from standard resistors • Uses 1 or 2 resistors in series or parallel (E6 to E96) • Best match first, with error % and tolerance range • Exclude values you don't have in your drawer • Send any result to the circuit builder in one tap SHARE AND SAVE • Export your circuit drawing and results table as an image • Share it or save it to Photos for assignments and notes • All your exported files stay in "My files": open, share, save, rename or delete HISTORY AND SAVED CIRCUITS • Every circuit is kept in History with the date • Save circuits with a name, then rename, duplicate or delete them • Search your circuits by name MADE THE WAY YOU LIKE • Light, dark or system theme • Choose 3 to 6 digits in answers • Engineering prefixes on or off (3.20 kΩ or 3197 Ω) • Pick your default E-series WORKS OFFLINE No internet needed, nothing to sign up for, no account. Your circuits stay on your phone. WHO IS IT FOR • Physics and electrical engineering students in school, college and university • Electronics hobbyists, makers and repair technicians • Teachers who want clear, step-by-step circuit examples Whether you need a simple series resistance calculator, a parallel resistance calculator, a resistor calculator with color code, a capacitor calculator, an inductor calculator or a full circuit solver for mixed series-parallel circuits, Series Parallel Circuit Solver gives you the right answer and shows you how it was found.
