About this app

Electronics Bench Toolkit is a practical electronics calculator for engineers, technicians, students, makers, and electronics hobbyists.

Solve common circuit calculations quickly with clear inputs, useful results, and visual circuit diagrams. Whether you are working at the electronics bench, studying circuit theory, prototyping a project, or checking component values, the toolkit keeps essential calculations in one place.

Electronics calculators included:

• Ohm’s Law Calculator:
Calculate voltage, current, or resistance from the other two known values.

• LED Resistor Calculator:
Calculate a suitable series resistor for an LED, including an E24 resistor recommendation and resistor power guidance.

• Resistor Color Code Calculator:
Decode 4-band, 5-band, and 6-band resistor color codes, including resistance, tolerance, and temperature coefficient where applicable.

• Voltage Divider Calculator:
Calculate output voltage from input voltage and resistor values with a clear voltage-divider circuit view.

• Series & Parallel Resistor Calculator:
Add multiple resistors and calculate equivalent resistance for series or parallel resistor networks.

Designed for practical electronics work

Electronics Bench Toolkit uses a clean, focused interface designed to make frequently used electronics calculations easy to access. Circuit illustrations help connect the calculation with the circuit being analyzed, while engineering units make it convenient to work with common resistor, voltage, and current values.

Electronics calculator app is useful for:

• Electronics engineers and technicians
• Electrical and electronics students
• Makers and DIY electronics enthusiasts
• Arduino and breadboard projects
• Circuit prototyping and troubleshooting
• Electronics coursework and bench calculations

Fast access to common circuit tools

Instead of switching between separate Ohm’s Law, resistor color code, LED resistor, voltage divider, and series/parallel resistor apps, Electronics Bench Toolkit brings these everyday tools together in one electronics utility.

Calculator inputs and results are processed locally on your device. No account or sign-in is required to use the electronics calculation tools.

Important note
Electronics Bench Toolkit is intended as an engineering and educational aid. Calculated values should be verified against component specifications, circuit requirements, and appropriate measuring equipment before use in a real circuit.
