What is done during continuity test?
A continuity test is a quick check to see if a circuit is open or closed. Only a closed, complete circuit (one that is switched ON) has continuity. During a continuity test, a digital multimeter sends a small current through the circuit to measure resistance in the circuit.

A continuity test is an important test in determining the damaged components or broken conductors in a circuit. It can also help in determining if the soldering is good, if the resistance is too high for flow of current or if the electrical wire is broken between two points.
What is a continuity test measured in?
resistance/ohms measurementA continuity test is like a simplified resistance/ohms measurement. A basic method is to apply a voltage across the resistor and measure the current OR apply a current and measure the voltage. Then through R = V/I you can calculate the resistance.
How does a multimeter check continuity?
The multimeter tests continuity by sending a little current through one probe, and checking whether the other probe receives it. If the probes are connected—either by a continuous circuit, or by touching each other directly—the test current flows through.
Can you test continuity on a live circuit?
Turn off and unplug the device that you're testing. Not only is it dangerous to test continuity when an active electrical signal is flowing through an outlet, wire, or power source, but it won't even work. Continuity is tested by sending a small current through the 2 terminals and reading the resistance on the current.

An ohmmeter is used to measure the resistance to electrical flow between two points. The ohmmeter is most commonly used to check continuity. Continuity is not a “measurement” as much as it is a yes/no statement. To say there is continuity is to say that there is a good electrical path between two points.
Why is continuity important in electrical?
Continuity can help you determine several things during the testing and troubleshooting phase: Determines if a circuit is open, closed, or shorted. Determines if a fuse is good or blown. Makes sure a switch is operating properly.

Risks of Introducing A Voltage Through The Multimeter Leads
- There is a risk of certain parts being damaged, especially parts that cannot tolerate the 1 to 9 volts that a multimeter might deliver across the probes in continuity mode.
- The above is especially true when the component (or other components on connected traces, which will also be affected) is not powered. Many parts can tolerate voltages when powered but not otherwise.
