Cutting Wires in a Circuit of Light Bulbs

AI Thread Summary
Cutting the wire at position B will cause the light bulb to become dimmer but not turn off, while cutting the wire at position D will completely turn off the light bulb as it disconnects from the circuit. Participants confirm these outcomes, with one seeking clarification on the reasoning behind the dimming effect at position B. The discussion emphasizes understanding circuit behavior in relation to wire connections. Overall, the responses validate the initial hypotheses regarding the impact of cutting wires on the light bulbs.

for What will happen if you cut the wire at position B?

I think The light bulb will become dimmer, but not go off. Am I correct?

for What will happen if you cut the wire at position D?

I think The light bulb will go off. (since the bulb was disconnected from the circuit) Am I correct?

The light bulb? Are we talking about the bulb that the hand is pointing to? If so, then you are right.

Correct.

I would be interested in your reasoning for the globe dimming when the wire is cur at B. You may have just made a lucky guess.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
