An instructor furiously cranks an electric generator to simultaneously power 5 electric light bulbs. Each 6.4 V bulb is drawing 0.24 A of current. Ignoring all resistance in the rest of the circuit, what is the power output of the instructor? Give your answer in watts.
Homework Answers
Solution:
Power output of all the electric bulbs
P = 5 ×(6.4)×(0.24) = 7.68 Watts
P = VI

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...

3. Suppose you were to build a circuit with two light bulbs in the same path. Will the total power delivered to the circuit be larger, smaller, or the same compared to the circuit with one light bulb (assume here that the battery has no internal resistance)? As you answer this, think about the product of current and potential difference for the battery. Explain (or try it out in the simulation and give your results!)

b. Three electric bulbs are connected in circuit with the 120 V battery as shown in the circuit diagram below . With the switch open (a) The manufacturer specifications for the cach bulb are 120V, 40W; 120V, 20W and 120V, 60W respectively. Using this specifications (means apply a 120 V to calculate the resistance of the bulbs), calculate the resistance of each bulb, note that the resistance of the bulbs remain constant. (R-360...
