How can continuity be tested in a circuit?

Testing for continuity in a circuit is primarily done by connecting a probe to each end of the circuit. This method allows you to determine if there is a complete path for current to flow. If continuity exists, the circuit will conduct electricity, often indicated by a tone from a continuity tester or a low resistance reading on a multimeter. This process helps identify any breaks in the circuit which would prevent the current from flowing.

Measuring voltage across components typically helps assess whether the correct voltage is present at a specific point, but it doesn’t directly confirm if there is a continuous path. Checking resistance at multiple points can indicate issues or the state of components, but it is more of a diagnostic approach than a direct continuity test. Analyzing current flow is helpful in understanding how current operates within the circuit but does not provide a confirmation of continuity on its own.
