Question

In the adjoining circuit, the e.m.f. of the cell is 2 volt and the internal resistance is negligible. The resistance of the voltmeter is `80 ohm`. The reading of the voltmeter will be

A. 0.80 volt
B. 1.60 volt
C. 1.33 volt
D. 2.00 volt

Answer 1

Correct Answer - C

`V_1 = (40)/(40 + 20) xx 2 = (4)/(3) V`
=`1.33 V`.
