V = Voltage (Volts)

Current Amps Draw Calculator Usage Guide

Learn how to use the Current Amps Draw Calculator and its working principles

How to Use This Calculator

  1. Enter the power consumption of your device in watts (W) in the "Power (Watts)" field.
  2. Enter the operating voltage of your device in volts (V) in the "Voltage (Volts)" field.
  3. Click the "Calculate" button to compute the current drawn by the device.
  4. The result will be displayed in the "Current (Amps)" field.

Working Principle

The calculator uses Ohm's Law to calculate current. The formula used is:

I = P / V

Where:

  • I = Current (in amps)
  • P = Power (in watts)
  • V = Voltage (in volts)

Example

For example, if you have a device that consumes 60 watts of power and operates at 120 volts, the current drawn would be:

I = 60 W / 120 V = 0.5 A

Applications

This calculator can be used for:

  • Estimating the current draw of household appliances
  • Designing electrical circuits and selecting appropriate wiring
  • Ensuring that power supplies and circuit breakers are adequately sized
  • Understanding energy consumption patterns
