Johtavuudencontinuitytesti, often referred to as a continuity test, is a method used to check the electrical continuity and resistance between two points in a circuit. This test is commonly employed in electronics and electrical engineering to ensure that components such as wires, connectors, and switches are functioning correctly. The test involves applying a low voltage to one point and measuring the voltage at the other point. If the circuit is continuous and there are no breaks or high resistances, the measured voltage should be the same as the applied voltage.

The continuity test is typically performed using a multimeter, which is a versatile tool that can measure voltage, current, and resistance. To conduct a continuity test, the multimeter is set to the ohms (Ω) or continuity mode. One probe is connected to the first point, and the other probe is connected to the second point. If the circuit is continuous, the multimeter will display a low resistance value, often less than 1 ohm. If there is a break or high resistance in the circuit, the multimeter will display an open circuit or a high resistance value.

Continuity tests are crucial in troubleshooting and maintaining electrical systems. They help identify faulty connections, loose wires, and other issues that can cause malfunctions or failures in electronic devices. By regularly performing continuity tests, technicians can ensure the reliability and safety of electrical circuits.
