1. What is Current to Voltage Conversion?

Current to voltage conversion is a fundamental concept in electrical engineering based on Ohm's Law, which states that the voltage across a conductor is directly proportional to the current flowing through it, with the constant of proportionality being the resistance.

2. How Does the Calculator Work?

The calculator uses Ohm's Law equation:

Where:

• \( V \) — Voltage in Volts (V)
• \( I \) — Current in Amperes (A)
• \( R \) — Resistance in Ohms (Ω)

Explanation: The equation shows the direct relationship between current and voltage when resistance is constant.

3. Importance of Voltage Calculation

Details: Accurate voltage calculation is crucial for circuit design, power management, and ensuring electrical components operate within their specified ranges.

4. Using the Calculator

Tips: Enter current in amperes and resistance in ohms. All values must be positive numbers. The calculator will compute the voltage drop across the resistor.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between AC and DC in this calculation?
A: The basic Ohm's Law applies to both, but for AC you must consider impedance (which includes resistance and reactance).

Q2: What happens if resistance is zero?
A: In theory, voltage would be zero, but in practice zero resistance would create a short circuit with potentially dangerous current flow.

Q3: Can I use this for non-ohmic materials?
A: No, Ohm's Law only applies to ohmic materials where resistance is constant regardless of voltage or current.

Q4: How accurate is this calculation?
A: It's mathematically precise for ideal resistors, but real-world components may have tolerance variations and temperature effects.

Q5: What units should I use?
A: The calculator uses base units (amperes, ohms, volts). For mA or kΩ, convert to base units first (1 mA = 0.001 A, 1 kΩ = 1000 Ω).
