Why Electric Tester does not work on DC Current?

Answer: Electric testers may not work on DC current due to their design for AC detection. They rely on the alternating nature of AC to induce a magnetic field, causing a response. DC lacks this alternating flow, rendering the tester ineffective. Reasoning: Electric testers, such as non-contact voltage testers, are …
