1. What is a Voltage to Ampere Calculator?

Definition: This calculator determines the electric current (in amperes) based on voltage and resistance using Ohm's Law.

Purpose: It helps electricians, engineers, and students quickly calculate current flow in electrical circuits.

2. How Does the Calculator Work?

The calculator uses Ohm's Law formula:

Where:

• \( I \) — Current (amperes)
• \( V \) — Voltage (volts)
• \( R \) — Resistance (ohms)

Explanation: The voltage is divided by the resistance to determine the current flowing through a circuit.

3. Importance of Current Calculation

Details: Proper current calculation ensures circuit safety, proper component selection, and efficient power distribution.

4. Using the Calculator

Tips: Enter the voltage in volts and resistance in ohms. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Ohm's Law?
A: Ohm's Law states that current through a conductor is directly proportional to voltage and inversely proportional to resistance.

Q2: What's a typical household voltage?
A: In most countries, household voltage is either 120V or 230V, depending on the region.

Q3: How do I measure resistance?
A: Resistance can be measured with a multimeter or calculated from material properties and dimensions.

Q4: What if I get zero resistance?
A: Zero resistance would theoretically result in infinite current (short circuit), which is dangerous in real-world applications.

Q5: Can I calculate voltage if I know current and resistance?
A: Yes, using the formula V = I × R. We have a separate calculator for this calculation.
