1. What is Electricity Load?

Electricity load in amps measures the current drawn by an electrical device or system. It's calculated by dividing power (in watts) by voltage (in volts).

2. How Does the Calculator Work?

The calculator uses the basic electrical formula:

Where:

• \( Power \) — Electrical power consumption in watts
• \( Voltage \) — Supply voltage in volts

Explanation: This formula comes from Ohm's Law and shows the relationship between power, voltage, and current.

3. Importance of Load Calculation

Details: Calculating electrical load is essential for circuit design, selecting proper wire sizes, choosing circuit breakers, and ensuring electrical safety.

4. Using the Calculator

Tips: Enter power in watts and voltage in volts. Both values must be positive numbers. The result will be the current in amperes (amps).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between real power and apparent power?
A: Real power (watts) is the actual power consumed, while apparent power (VA) includes reactive power. This calculator uses real power.

Q2: How does this apply to AC circuits?
A: For purely resistive AC loads, this formula works directly. For reactive loads, power factor must be considered.

Q3: Why is load calculation important?
A: Proper load calculation prevents circuit overloads, reduces fire risk, and ensures electrical devices work efficiently.

Q4: What are typical household voltages?
A: In North America, 120V for most circuits and 240V for large appliances. Europe typically uses 230V.

Q5: How do I calculate load for multiple devices?
A: Calculate each device's load separately, then sum them to get the total circuit load.
