Calculating amps from watts and volts is a simple process that is essential for anyone who works with electrical appliances. Whether you are an electrician, an engineer, or a regular person who wants to understand the basics of electricity, this guide will teach you how to calculate amps from watts and volts.
Understanding the Basics
Before we dive into the calculations, let’s first understand the basics of electricity. The three main components of electricity are volts, amps, and watts. Volts measure the electrical pressure or force, amps measure the amount of electrical current, and watts measure the electrical power. In other words, volts are the potential, amps are the flow, and watts are the combination of both.
Formula for Calculating Amps
The formula for calculating amps from watts and volts is:
Amps = Watts / Volts
This formula is also known as Ohm’s law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
Example Calculation
Let’s say you have a 100-watt light bulb that is connected to a 120-volt power source. To calculate the amps, you would use the formula:
Amps = 100 / 120
which gives you:
Amps = 0.83
Therefore, the 100-watt light bulb draws 0.83 amps of current when connected to a 120-volt power source.
FAQs
