Question

how to find reading of voltmeter when it is connected with a resistance​

Answer 1

Explanation:

Now the resistances 200 ohms, 100 ohms and the combined resistance of 200 ohms are all connected in series. So the total resistance is 200+100+200 = 500 ohms. Now, the current through the circuit is calculated as I=V/R = 100/500 = 0.2 A. The voltmeter of 600 ohms is connected across the 300 ohms resistance

Answer 2

Answer: If there a potential diff. is generated in circuit, then see the reading in the scale

This is the potential difference....
