Three identical light bulbs labeled A, B and C are connected to a battery as shown in the circuit below. When the switch is closed, which of the following statements is true about the currentthrough the light bulbs?
A. No current flows through bulbs B and C because the B/C loop does not contain a battery. Only A has a current running through it.
B. The current through A is equal to the sum of the currents through B and C.
C. The current through A is equal to either the current through B or the current through C.
D. The current through all three light bulbs is the same.

A simple series circuit consists of three identical bulbs, a
battery, and a wire with a switch as shown in the diagram. When the
switch is open, all three bulbs glow with the same brightness. Then
the switch is closed. When the switch is closed, the brightness of
bulb A (increased, decreased, remained the same), and the current
through the battery (increased, decreased, remained the same).
Pick the right answer and explain your
reasons.

A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...
