alleryAn ammeter is connected in series in a circuit because
Ait must measure the same current that flows through the conductor
Bit has very high resistance and must avoid current
Cit measures potential difference across the conductor
Dit works only when connected parallel to a battery
Answer & Solution
Correct answer: A. it must measure the same current that flows through the conductor
Current is the same through all elements connected in series
so an ammeter is placed in series with the conductor whose current is to be measured.
Since it has low resistance, it minimally affects the current.
