Answer: Megger is preferred over a multimeter for insulation testing because it applies a higher voltage, typically 500V or more, which is necessary to accurately assess the insulation resistance and detect potential faults. Reasoning: Insulation testing requires the application of a higher voltage to accurately measure the resistance of insulation …

Answer: If you touch both terminals of a 12V battery, you create a closed circuit, allowing current to flow through your body, potentially causing electric shock, burns, or even death. Reasoning: When you touch both terminals of a 12V battery, you complete the circuit, allowing electricity to flow through your …
