In the circuits below, all bulbs are identical, and all batteries are ideal and identical. A B 1. Consider the circuit at right. Note that the middle battery is not connected in the same way as the other two. Rank bulbs A-C according to brightness, from largest to smallest. If any bulbs are equal in brightness or if any bulbs are not lit, state so explicitly. Explain. с

Two batteries, a capacitor, and two light bulbs are connected by
wires. The batteries have a potential difference emf, the capacitor
has capacitance C, and the bulbs have resistance R. Initially the
capacitor is uncharged and the switch has been closed.

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...

A circuit is made of two 1.4 volt batteries and three light bulbs as shown in the figure. When the switch is closed and the buibs are glowing, bulb I hasa resistance of 11 ohms, bulb 2 has a resistance of 44 ohms, bulb 3 has a resistance of 26 ohms, and the copper connecting wires have negligible resistance. You can also neglect the internal resistance of the batteries (a) With the swtch open, indicate the approximate surface charge on...

1.A single light bulb is connected to a 12 V battery. The light bulb uses 55 W of power (which is about what a car’s headlight uses). (a) What is the current flowing out of the high-voltage (+) end of the battery? (b) What is the current flowing into the low-voltage (-) end of the battery? (c) The battery has a sticker on it that says “This 12V battery contains 50 Amp-hours.” This indicates Amps × hours that the battery...

A Investigation #11: Non-Identical Bulbs in Series and Parallel All of the circuits you have investigated so far have involved identical bulbs. If two bulbs are identical and one bulb is brighter, then the brighter bulb must have a larger current thru it. Furthermore, the larger current must be caused by a larger potential difference. In this investigation, you will study circuits for which the bulbs are not identical. We will illustrate that two Spherical bulbs are not identical by...
