a.When two resistors RA and RB are combined in series and connected to a battery it is observed that the ratio of the power dissipated in RA to that dissipated in RB is equal to 10. If this arrangement is dismantled and the same two resistors connected in parallel to the same battery, what is the ratio of the power dissipated in RA to that dissipated in RB in this new circuit? b.How much energy is converted by a 12...

an ideal battery. Assume that the resistance of each light bulb
remains constant. Rank the bulbs (A through E) based on their
brightness.

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...
