The D’Arsonval galvanometer measures:

• Voltage

• Resistance

• Current

• Power

What is the purpose of a shunt resistor in an ammeter?

• To increase sensitivity

• To decrease the meter’s range

• To allow large currents to bypass the galvanometer

• To measure voltage

For a voltmeter, why is a large series resistor used?

• To increase current flow

• To prevent meter damage and limit current

• To measure resistance

• To reduce voltage

Which statement about an ideal voltmeter is correct?

• It has zero resistance

• Across the power supply

Where should an ammeter be connected in a circuit?

• Across the battery only

• In series with the load

• Across the load only

• Across the resistor only
