How do you measure DC voltage and current using a multimeter?
Understand the Problem
The question is asking about the process or method to measure direct current (DC) voltage and current using a multimeter. This involves understanding the appropriate settings on the multimeter and the correct connections for measuring voltage and current. Essentially, it is about how to use a multimeter effectively.
Answer
For DC voltage, set multimeter to DCV, probes in parallel. For DC current, set to DCA, probes in series.
To measure DC voltage with a multimeter, set it to the DC voltage setting, usually denoted by 'V' or 'V—'. Insert the red probe into the 'VΩ' jack and the black probe into the 'COM' jack. Connect the probes in parallel across the component to measure voltage. For DC current, set the multimeter to the DC current setting, denoted by 'A—', insert the red probe into the 'A' jack and the black probe into the 'COM' jack, and connect the probes in series with the circuit.

More Information
A multimeter is an essential tool for measuring electrical properties like voltage, current, and resistance in circuits. Knowing how to measure these correctly ensures accurate diagnostics.
Tips
Confusing the positioning of the probes: Probes must be placed correctly depending on the measurement type. Ensure proper series or parallel connection when measuring current or voltage, respectively.
