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...
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.
