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 consists of a 3-volt battery; connecting wires with very low resistivity; a light bulb with resistance = 2Ω. a. How much current is flowing through the bulb? b. How much energy per second is converted from electrical potential energy to light and heat? c. If the bulb is replaced with one with higher resistance, in what way (increase, decrease, stay the same) would voltage and current change?

Complex Circuit problem.
3- Complex electric circuit Three equal resistors R are connected to a battery as shown in the figure below. The electric potential across the battery terminals when unconnected to this circuit is 9 V. Considering a value of r # 0.5 Ω for the internal resistance of the battery and a value of R- 5.5 2 for the three resistors, find 1. the voltage across the battery terminals when the switch is open 2. the voltage across...

You obtain a 50-and a 100-W light bulb. Instead of connecting them in the normal way, you devise a circuit that places them in series across normal household voltage. If each one is an incandescent bulb of fixed resistance, which statement about these bulbs is correct? Both bulbs glow with the same brightness, but more than their normal brightness. The 100-W bulb glows brighter than the 50-W bulb. The 50-W bulb glows more brightly than the 100-W bulb, Both bulbs...
