Two resistors are connected in series across a battery as shown in figure. If a voltmeter of resistance 2000 Ω is used to measure the potential difference across 500 Ω resister, the reading of the voltmeter will be _____ V

Correct answer

0

Step-by-step solution

The voltmeter resistance is given to be 2000   Ω . The equivalent resistance in the given circuit is R e q = 500 × 2000 2000 + 500 + 600 = 1000   Ω . Now, current in the circuit is i = 20 1000   A . Reading of the voltmeter will be, V = 20 - 600 × 20 1000 = 8   V
