Question 17

Two parallel branches are connected across a 24 V DC supply:

  • The left branch has a 20 Ω resistor between the positive terminal and point XXX, and a 10 Ω resistor between X X\,X and the negative terminal.
  • The right branch has a 10 Ω resistor between the positive terminal and point YYY, and a 30 Ω resistor between Y Y\,Y and the negative terminal.

What is the reading on an ideal voltmeter connected between points X X\,X and YYY?

A

2 V2\text{ V}2 V

B

C

10 V10\text{ V}10 V

D
