Homework Statement
A main circuit contains six similar bulbs connected in series. One of the bulbs has a broken filament. Voltmeters X and Y of infinite resistance are placed in the circuit as shown.
What are the voltmeter readings?
A) X=0 Y=0
B) X=0 Y=240
C) X=40 Y=40
D) X=240 Y=0
Homework Equations
None
The Attempt at a Solution
Answer: D.
This is my reasoning:
A broken filament has infinite resistance because no current can flow. So the it would "draw" all the voltage from the source.
Am I correct?
Also, I would like to ask, why can't the first bulb light up? Since the source is continuously supplying a current, and the current should pass through the first bulb first before passing the second bulb.
Thank you.
