How to Use This Calculator
  1. Select the calculator mode: Ohm's Law, Voltage Drop, Resistor Color Code, or Series/Parallel.
  2. For Ohm's Law: enter two of voltage (V), current (A), and resistance (R) to find the third.
  3. For Voltage Drop: enter source voltage, current, wire length, and AWG to find the drop.
  4. For Color Code: select band colors to decode resistor value and tolerance.
  5. Review results and use in circuit design, troubleshooting, or electrical coursework.
