Chapter 26, Problem 26.55P

The two identical light bulbs in Example 26.2 (Section 26.1) are connected in parallel to a different source, one with ε = 8.0 V and internal resistance 0.8 Ω. Each light bulb has a resistance R = 2.0 Ω (assumed independent of the current through the bulb), (a) Find the current through each bulb, the potential difference across each bulb, and the power delivered to each bulb, (b) Suppose one of the bulbs bums out, so that its filament breaks and current no longer flows through it. Find the power delivered to the remaining bulb. Does the remaining bulb glow more or less brightly after the other bulb burns out than before?

Consider the network of four resistors shown in the diagram, where R1 = 1 Ω, R2 = 5 Ω, R3 =2Ω,andR4 =6Ω. . The resistors are connected to a battery with an emf V. (a) What is the current flowing out of the battery if the emf is 12 V? (B) What is the voltage difference across the resistor R1? (C) What is the rate of Ohmic dissipation for resistor R2?

Consider the circuit shown that has two resistors (each with resistance R = 8.00 Q), a battery with negligible internal resistance (V= 12.0 V), and a lightbulb. If the resistance of the lightbulb is 3.50 Q, calculate the power output of the lightbulb (ie. the rate at which energy is dissipated in the lightbulb). R R 12 W 2.2 W 6.8 W 4.0 W
