An ammeter with internal resistance

90\,\,\mathrm{\Omega }

reads

1.85\,\,A

when connected in a circuit containing a battery and two resistors

700\,\,\mathrm{\Omega }

and

410\,\,\mathrm{\Omega }

in series. Actual current will be

View answer and explanation

Correct option: B

Greater than

1.85\,\,A

The correct answer is Greater than

1.85\,\,A

because the ammeter's internal resistance reduces the total resistance in the circuit, thus lowering the current reading.
