Final answer:
The indicator on a multimeter will always display a reading when measuring DC voltage across a device. This is true because a multimeter is specifically designed to measure voltage in a circuit.
Step-by-step explanation:
When measuring DC voltage across a device with a multimeter, the indicator will always display a reading. This statement is True. A multimeter is used to measure voltage, current, and resistance in a circuit. When measuring voltage, the multimeter is connected in parallel with the device and provides an accurate reading of the voltage across the device.
