Defend, dispute or clarify this statement: “Adding bulbs to a circuit increases the total resistance.” You should write an explanation and support your position with one or more circuit diagrams.
Homework Answers
No ,it depends on whether bulbs are added in parallel or series. if bulbs are added in series ,total resistance increases and if bulbs are added in parallel in total resistance decreases .For example consider the circuit

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!)

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...
