Amps to Volts Calculator

What is the relationship between Amps and Volts?

Amperage (measured in amps) and voltage (measured in volts) are two fundamental concepts in electrical engineering. They are related through Ohm's Law, which states that voltage equals current multiplied by resistance (V = I × R), or through the power equation, which states that power equals voltage multiplied by current (P = V × I).

How to convert Amps to Volts

To convert amps to volts, you need to know either the power (watts) or the resistance (ohms) in the circuit. Here are the two methods:

1. Using Watts: V = W / A
2. Using Ohms: V = A × R

Where V is voltage (volts), A is current (amps), W is power (watts), and R is resistance (ohms).

Examples

Let's look at two examples:

1. Using Watts: If a device draws 2 amps and consumes 240 watts, what is the voltage?

   V = W / A = 240 / 2 = 120 volts

2. Using Ohms: If a 3-amp current flows through a 20-ohm resistor, what is the voltage?

   V = A × R = 3 × 20 = 60 volts

Applications

Understanding the relationship between amps and volts is crucial in many areas, including:

• Electrical engineering and circuit design
• Home wiring and appliance usage
• Battery and power supply specifications
• Solar panel and renewable energy systems

This calculator simplifies the process of converting between amps and volts, making it a valuable tool for professionals and hobbyists alike in the field of electronics and electrical engineering.
