## What is VoltBench?

Keep common low-voltage circuit calculations in one place. Check a resistor network, choose a current-limiting resistor for an LED, then save the result for the next bench session.

• Calculate resistance, total current and power for series or parallel networks of 2–12 resistors.
• Find an LED resistor, the next usable E12 value, estimated current and minimum power rating with a 2× margin.
• Name, search, reopen and share saved calculations. Formula cards explain units and assumptions.
