What is the voltage reading when the selector is in the 30 DCV position?

• A. 2 VDC
• B. 3 VDC
• C. 5 VDC
• D. 4 VDC

Answer: (A)

In this context, when the selector is in the 30 DCV position, it indicates that the multimeter is set to measure voltage in a range that allows for a maximum reading of 30 volts in direct current (DC). The answer of 2 VDC implies that the measured voltage in the circuit is 2 volts, which is within the permissible range of the 30 DCV setting. When using a multimeter, each setting corresponds to a certain range of measurable values. A reading of 2 VDC means that the voltage present in the circuit being tested is 2 volts. This reading is clear and accurate within the selected range and reflects the basic functionality of measuring electrical voltage. Different voltage readings during measurement (like 3 VDC, 5 VDC, or 4 VDC) fall outside the stated reading of 2 VDC and may not accurately reflect the actual condition of the circuit under test at that moment if chosen as the answer. Thus, 2 VDC correctly indicates a plausible and valid voltage measurement under that selected range.
