Besides measuring specific resistances, list three or more electrical problems for which ohmmeters can be used to check. 2. Why must only a single wire of a circuit be placed in the jaws of a clamp-on ammeter? 3. What is the purpose of shunt resistors in an in-line ammeter? 4. Before taking a voltage or current measurement, explain some of the checks you should do to prevent accidentally damaging the meter. 5. Explain why it is best to completely remove a device from its circuit when measuring its resistance.
