Q1:

Two voltmeters are each 0-300 V range. Their internal resistances are 10 kΩ and 20 kΩ They are connected is series and a voltage of 400 V is applied. Their readings respectively will be

A 266.6 and 133.3 V

B 133.3 and 266.6 V

C 200 V each

D 100 and 300 V

ANS:B - 133.3 and 266.6 V

The readings will be proportional to their internal resistance, .
