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.

The three light bulbs in the circuit all have the same resistance. Given that brightness is proportional to power dissipated, the brightness of bulbs B and C together, compared with the brightness of bulb A, is Twice as much, the same, half as much? The light bulbs in the circuit are identical. When the switch is closed, 12 V 12 VF Both lamps go out The intensity of light bulb...
