How to Check Continuity for Beginners

Introduction: How to Check Continuity for Beginners

About: Hello friends i show how to make stuff with no skills easy to replicate step by step from powerbanks,generator,invertors and so on thanks

Hi there you always hear check for continuity or you can find but first do a continuity test.Today i will explain for beginners how to check continuity with a digital multimeter, you know the orange box that is in all youtube clips...

A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analog multimeters use a microammeter with a moving pointer to display readings. Digital multimeters (DMM, DVOM) have a numeric display, and may also show a graphical bar representing the measured value.

Step 1: How to Use a Multimeter for Beginners

This is a basic tutorial and many of you know this stuff already, but for the beginner that has a passion for electronics they have to start from somewhere and that is learning the basic knowledge, tools, and physics.

In electronics, a continuity test is the checking of an electric circuit to see if current
flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path. If electron flow is inhibited by broken conductors, damaged components, or excessive resistance, the circuit is "open".

Devices that can be used to perform continuity tests include multimeters which measure current and specialized continuity testers which are cheaper, more basic devices, generally with a simple light bulb that lights up when current flows.

Step 2: The Rope Concept

Now think like this to perform a continuity test you will need a multimeter and the idea is to think of the path that you want to test as a rope, or a long continuous wire.If the rope is not broken that means is a continuous rope or in electronics its got continuity.When we cut that wire in half it has no continuity as a full rope(continuity remains in the small pieces).It's very simple but misunderstood by many hobbyists.

Step 3: Multimeter Symbol for Continuity

In the picture above you have the symbol for continuity(it may vary from meter to meter.

Continuity test(check) can be used in many practical applications:

-Continuity of a wire or circuit path

-Car fuses or house fuses(not translucid ones)

-Bulb you can check if the bulb is working or not

-Transformers multi windings
