An ammeter is connected in series in a circuit because it must
Ameasure the potential difference across the component
Ballow only a small fraction of current to pass
Ccarry the same current as the conductor in which current is being measured
Dincrease the effective resistance of the circuit
Answer & Solution
Correct answer: C. carry the same current as the conductor in which current is being measured
To measure current through a conductor, the ammeter must be placed in series so that the same current passes through both the conductor and the meter. A parallel connection would not measure the intended current correctly.
