Understanding Ammeter and Voltmeter Connections

What is the primary function of an ammeter in a circuit?

• To measure power

• To measure current

• To measure resistance

• To measure voltage

How should an ammeter be connected in a circuit to measure current accurately?

• In parallel with the power source

• In series with the resistor

• In parallel with the resistor

• In series with the voltmeter

What happens if an ammeter is connected in parallel with a resistor?

• It will measure the voltage

• It may get damaged or give incorrect readings

• It will measure the power

• It will measure the resistance

Where should a voltmeter be connected to measure the potential difference across a resistor?

• In parallel with the ammeter

• In series with the power source

• In parallel with the resistor

• In series with the resistor

What does the potential difference between two points in a circuit represent?

• The resistance between the points

• The current flowing between the points

• The power consumed between the points

• The amount of work done to move a charge between the points
