Understanding Ammeters in Circuits

What is the primary function of an ammeter?

• To measure voltage in a circuit

• To measure the amount of current flowing in a circuit

• To measure resistance in a circuit

• To measure power consumption in a circuit

Which type of ammeter is most commonly used in residential electrical work?

• In-line ammeter

• Clamp-on ammeter

• Digital ammeter

• Analog ammeter

Why are in-line ammeters seldom used in electrical construction work?

• They are too expensive

• They do not have high enough amperage ratings

• They are not accurate

• They are too large

What can ammeters be used to locate in a circuit?

• Voltage drops

• Overloads and open circuits

• Short circuits

• Power surges

What is one advantage of using a clamp-on ammeter over an in-line ammeter?

• It is more accurate

• It is easier to use

• It is cheaper

• It is smaller
