Watt to Volt Formula:
From: | To: |
The Watt to Volt conversion calculates electrical voltage from power (in watts) and current (in amps). This is based on the fundamental electrical formula V = W / A.
The calculator uses the formula:
Where:
Explanation: This formula is derived from the basic electrical power equation P = IV (Power = Current × Voltage).
Details: Knowing voltage is essential for circuit design, electrical safety, and ensuring compatibility between power sources and devices.
Tips: Enter power in watts and current in amps. Both values must be positive numbers. The calculator will compute the voltage.
Q1: What's the difference between watts and volts?
A: Watts measure power (energy per unit time), while volts measure electrical potential difference.
Q2: Can I calculate watts if I know volts and amps?
A: Yes, using W = V × A. This calculator can be rearranged to solve for any of the three variables.
Q3: What is a typical household voltage?
A: In most countries, household voltage is either 110-120V or 220-240V, depending on location.
Q4: Why would I need to calculate voltage from watts?
A: This calculation is useful when designing circuits or determining power requirements for electrical devices.
Q5: Is this calculation valid for both AC and DC?
A: This simple formula works for DC circuits. For AC, you need to consider power factor as well.
