I have been going through some past questions for my exam that is coming up this summer. I have come across this question which I originally deemed to be easy however the more I have looked over it the more I believe I am confusing myself and over complicating things!
This is the question I am looking at:
My current thought process is that the voltage across Bulb A will not change when Bulb B is removed, however the current which previously was split between the two branches of the circuit (Kirchoff's Current Law?) will now all flow through Bulb A and its resistor.
This lead me to believe that if the current effectively doubles and the voltage stays the same then P = IV will mean that the power dissapated in Bulb A will also increase. This means that Bulb A is now brighter? and the answer would therefore be C.
I am asking if this thought process is correct? or if I have simply confused myself and gotten it wrong! If that is the case I would love for someone to explain the answer to me so I can understand it and attempt other questions like this.
