When to use AC or DC on multimeter?
2 Answers
When using a multimeter, you'll choose AC or DC depending on the type of voltage or current you're measuring:
1. **AC (Alternating Current)**:
- Use when measuring household electrical outlets, appliances, or any circuit powered by mains electricity (like 120V or 240V).
- Common in circuits with devices like fans, lights, and other electrical appliances.
2. **DC (Direct Current)**:
- Use for measuring batteries, electronic devices, or circuits that operate on battery power (like 9V batteries, solar panels, etc.).
- Also used in most low-voltage electronics (like smartphones and laptops).
### Quick Tips:
- Check the device specifications to determine if it uses AC or DC.
- For signals from electronic components (like in audio or communication devices), check if they are designed for AC or DC operation.
Always start with the appropriate setting to avoid damaging the multimeter!
