Understanding Voltage Conversion

Converting amperes to volts is fundamental in electrical calculations. There are two main methods:

Power Method (V = P/I)

When you know the power consumption:

  • V (Volts) = P (Watts) ÷ I (Amps)
  • Example: 100W ÷ 2A = 50V

Resistance Method (V = IR)

Using Ohm's Law:

  • V (Volts) = I (Amps) × R (Ohms)
  • Example: 2A × 25Ω = 50V
