An ammeter is inserted in _______
A. Series in a circuit and current to be measured flows through it
B. Series in a circuit and part of the current to be measured flows through it
C. Parallel in a circuit and current to be measured flows through it
D. Parallel in a circuit and only part of the current to the measured flows through it.
Show Answer
Answer: A
Explanation:-
An ammeter is connected in series with the load To measure current, you want most of the current to pass through it. Hence ammeter is connected in series with the low resistance.
An ammeter measures the value of current flowing in the circuit, so current should flow inside ammeter to give proper result. it acts like a closed switch so it indicates the current. And it has very low resistance to ensure the correct measurement of current in the circuit. If it is connected in parallel across any load then all current in the circuit will choose the lower resistive path (i.e ammeter) to cause its circuit to be damaged. Hence it is used in series.
