1. What is the Voltage Formula?

The voltage formula V = W/Q calculates electrical potential difference from work done and electric charge. It represents the energy transferred per unit charge between two points in an electrical circuit.

2. How Does the Calculator Work?

The calculator uses the voltage formula:

Where:

• \( V \) — Voltage (volts)
• \( W \) — Work or energy (joules)
• \( Q \) — Electric charge (coulombs)

Explanation: This formula shows the fundamental relationship between electrical potential, energy, and charge in electrical systems.

3. Importance of Voltage Calculation

Details: Accurate voltage calculation is essential for designing electrical circuits, analyzing power systems, and understanding electrical potential differences in various applications.

4. Using the Calculator

Tips: Enter work in joules and charge in coulombs. Both values must be positive numbers greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of voltage?
A: Voltage is measured in volts (V), which is equivalent to joules per coulomb (J/C).

Q2: Can voltage be negative?
A: Yes, voltage can be negative when indicating the direction of potential difference relative to a reference point.

Q3: What is typical voltage range?
A: Common voltages range from millivolts (mV) in biological systems to kilovolts (kV) in power transmission systems.

Q4: How does voltage relate to current?
A: Voltage is the driving force that causes electric current to flow through a conductor, as described by Ohm's Law (V = I × R).

Q5: Is this formula applicable to AC circuits?
A: While the fundamental relationship holds, AC circuits require additional considerations for RMS values and phase relationships.
