Question

Differences between voltmeter, ammeter, ohmmeter?

Choose which of the three meters the following apply to:

the circuit must be on

can measure a resistor only in a circuit

can measure a resistor out of the circuit

---

Since our teacher never once talked about these meter things, I need serious help here...

Answer

the circuit must be on - amp-meter. if the circuit isn't drawing current, there's nothing to measure.

can measure a resistor only in a circuit - voltmeter. can measure voltage drop across a resistor.

can measure a resistor out of the circuit - ohmmeter. measures resistance.
