Chapter 6.1, Problem 3aT
Compare the brightness of the bulbs in this circuit.
1. What can you conclude from your observation about the amount of current through each bulb?
2. Describe the current in the entire circuit. Base your answer on your observations. In particular, how does the current through the battery seem to divide and recombine at the junctions of the two parallel branches?

please answer both question in type form ( need for my project)
In each circuit, rank the bulbs according to brightness. If any bulbs are equal in brightness or not lit, state so explicitly. Explain your reasoning. (Assume all bulbs are identical and all batteries are ideal).
a.)
A circuit contains three identical bulbs lit by connection to a single battery. When a wire is connected across the terminals of one of the bulbs, it goes out and so does another one of the bulbs. The remaining bulb becomes brighter.
a.) Sketch the circuit in which the two bulbs must have been arranged. Explain reasoning
b.) What would happen to the brightness of the other two bulbs if the wire were connected across the terminals of the bulb that does not go out in part (a)?
Three resistors having resistances of 4.0 Ω, 6.0 Ω, and 10.0 Ω are now connected in series. If the combination is connected to an ideal 12-V.
What is the total resistance of the circuit?
What is the current through each resistor?
What is the voltage drop across each resistor?
What is the power dissipated by the 6.0 Ω resistor?
Clearly state the formulae you’re using and what your letters/symbols mean.
