Understanding the Volts to Amps Calculator

The Volts to Amps Calculator helps calculate the electric current in a circuit based on the provided voltage and resistance. The calculation is based on Ohm's Law, a fundamental principle in electronics.

Formula for Calculating Current

The current is calculated as:

\( I = \frac{V}{R} \)

Where:

• \( I \) = Current in Amps (A)
• \( V \) = Voltage in Volts (V)
• \( R \) = Resistance in Ohms (Ω)

Example Calculations

Example 1: Basic Calculation

Given: Voltage (\( V \)) = 12 V, Resistance (\( R \)) = 4 Ω

\( I = \frac{V}{R} = \frac{12}{4} = 3 \, \text{A} \)

The current in the circuit is \( 3 \, \text{A} \).

Example 2: Using Millivolts and Kilohms

Given: Voltage (\( V \)) = 200 mV, Resistance (\( R \)) = 2 kΩ

Convert units: Voltage = \( \frac{200}{1000} = 0.2 \, \text{V} \), Resistance = \( 2 \, \text{k}\Omega = 2000 \, \Omega \)

\( I = \frac{V}{R} = \frac{0.2}{2000} = 0.0001 \, \text{A} \, (100 \, \text{mA}) \)

The current in the circuit is \( 100 \, \text{mA} \).
