When using a multimeter to measure voltage, how should the probes be connected?

The correct approach when measuring voltage with a multimeter involves connecting the probes in parallel with the power source or across the component where the voltage reading is desired. This means that one probe is connected to the positive side and the other to the negative side of the circuit or component. This configuration allows the multimeter to effectively measure the potential difference between those two points without interrupting the flow of current through the circuit.

Connecting the probes in parallel enables the multimeter to accurately capture the voltage level present without affecting the operation of the circuit. If the probes were connected in series with the load, the multimeter would become part of the circuit, potentially leading to inaccurate readings and possibly damaging the multimeter if the current exceeds its rating. Connecting directly to the battery terminals provides a specific reading, but it may not reflect the voltage drop across a load in a functioning circuit. Finally, creating a loop with the circuit is not a standard method for measuring voltage and would likely misconstrue the reading or malfunction. Thus, connecting the probes in parallel with the power source is essential for correct voltage measurement.
