Question

47. In order to measure current in a resistance present in a circuit, the ammeter is connected
(A) in series
(B) in parallel
(C) in series or parallel
(D) nothing can be decided​

Answer 1

Answer:

in series i guess

Explanation:

not sure

Answer 2

Answer:

Option (A)

Explanation:

An ammeter must always be connected in series. Assume we did connect an ammeter in a parallel configuration.

Then, the current, we know, would branch out at the diversion based on the ratios of the resistance of ammeter (although negligible, it still does) and the resistance in the circuit itself. Thus, the maximum value of the current cannot be obtained. Hence, An ammeter must always be placed in series to obtain the maximum, i.e., the actual current flowing through the circuit.

Therefore, Option (A) is valid.
