What is the voltage and wattage of the resistor when testing for ground in a DC circuit?

• A. 10k ohms and 5 watts
• B. 15k ohms and 1 watt
• C. 5k ohms and 10 watts
• D. 1k ohms and 15 watts

Answer: (B)

In testing for ground in a DC circuit, the values of resistance and wattage selected for the resistor play a crucial role in ensuring safe and effective testing. The resistance value of 15k ohms indicates a higher impedance, which reduces the current flowing through the circuit. This is particularly important in a testing scenario, as it helps prevent damage to sensitive components. The wattage of 1 watt suggests that the resistor is capable of handling the power dissipation without overheating or failing. In a typical DC circuit when testing for ground, it's essential to limit the current to avoid potential harmful surges that could affect other components. This combination of a relatively high resistance and low wattage is appropriate for ensuring that the testing process does not inadvertently introduce too much current, which could disrupt the circuit under examination or lead to inaccurate measurements. Thus, the selection of 15k ohms and 1 watt serves a practical purpose in maintaining the integrity of the circuit being tested while effectively detecting grounding issues.
