Formulas Used

The calculator uses the following formulas depending on the selected calculation type:

• Amps to Volts with Watts: Where:
  • V is voltage (in volts),
  • P is power (in watts),
  • I is current (in amps).
• Amps to Volts with Ohms: Where:
  • V is voltage (in volts),
  • I is current (in amps),
  • R is resistance (in ohms).

Example Calculations

1. Watts-Based Calculation:
   • Current: 5 amps Power: 100 watts

      

   Voltage = 20 volts.
2. Ohms-Based Calculation:
   • Current: 2 ampsResistance: 50 ohms

      

   Voltage = 100 volts.
