What is the voltage and wattage of the resistor when testing for ground in an AC circuit?

• A. 5k ohms and 10 watts
• B. 2k ohms and 15 watts bigger
• C. 1k ohms and 5 watts
• D. 20k ohms and 25 watts

Answer: (B)

In testing for ground in an AC circuit, the resistor plays a crucial role in achieving the necessary voltage and wattage ratings to safely determine the presence of a proper ground connection. The correct response indicates a resistor rated at 2k ohms and 15 watts, which is appropriate for handling the electrical characteristics typically found in many AC circuits. A 2k ohm resistor strikes a balance between providing enough resistance to limit current and allowing enough voltage to be measured across it for reliable testing. The 15-watt rating is significant as it indicates the resistor can handle the power without overheating or failing, which is essential when dealing with fluctuating currents and voltages in AC applications. When testing for ground, using a resistor with adequate wattage is essential to ensure safety and precision. If a resistor with too low a wattage rating were to be used, it might overheat or damage, leading to unreliable test results. Therefore, the choice of 2k ohms and 15 watts represents a suitable option for ensuring consistent and safe measurements in an AC circuit environment.
