- A wire is added as shown to the original circuit.
What is wrong with the following reasoning?
The top right bulb will go out, because its two sides are now connected with wire, so there will
be no voltage difference across it. The other three bulbs will not be affected.
- A wire is added as shown to the original circuit.
What is wrong with the following reasoning?
The current flows out of the right side of the battery. When it hits the first junction, some of
it will go left and some will keep going up The part that goes up lights the top right bulb. The
part that turns left then follows the path of least resistance, going through the new wire instead
of the bottom bulb. The top bulb stays lit, the bottom one goes out, and others stay the same.
- What happens when one bulb is unscrewed, leaving an air gap?
