Amp to Volt Conversion
Formula 1: Amp to Volt using Power (Watts)
To calculate voltage when current (I) and power (P) are known:
\[ V = \frac{P}{I} \]
Where:
- \(V\) = Voltage in volts
- \(P\) = Power in watts
- \(I\) = Current in amps
Formula 2: Amp to Volt using Resistance (Ohms)
To calculate voltage when current (I) and resistance (R) are known:
\[ V = I \times R \]
Where:
- \(V\) = Voltage in volts
- \(I\) = Current in amps
- \(R\) = Resistance in ohms
Example Calculation 1: Using Power
If the current is 5 amps and power is 100 watts:
\[ V = \frac{100}{5} = 20 \text{ volts} \]
Example Calculation 2: Using Resistance
If the current is 5 amps and resistance is 4 ohms:
\[ V = 5 \times 4 = 20 \text{ volts} \]
