Q. An ammeter with internal resistance $90\Omega$ reads $1.85\ A$ when connected in a circuit containing a battery and two resistors $700\Omega$ and $410\Omega$ in series. Actual current will be
A) $1.85\ A$
B) Greater than $1.85\ A$
C) Less than $1.85\ A$
D) None of these
Explanation
(b) In general, ammeter always reads less than the actual value because of its resistance
