Using the picture above, as a reference, think and predict what will occur int he following scenarios.
3.2.1 You have three resistances with different values, both setups connected to a power supply set at equal voltage.
? Which of the setups has the greater overall resistance : A or B
Explain your reasoning.
3.2.2 You only have access to the set up A controls. What do you have to do, to have the same current in both setups?. Lower Voltage of A, or Rise the voltage in B.
Explain your reasoning.
Homework Answers
B has a greater overall resistance as all resistance in B are in series while in A these are in parallel.
as resistance of A is less than B so for same current we have to lower the voltage of A as we can only control set up A

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...

Have you ever wanted to predict the future? Well the Magic Eight Ball does just that. The original game was a softball sized “8-ball”. You would ask a question, shake it up and look at the result. There are 20 responses…10 positive, 5 negative, and 5 are vague. For this project, we want to recreate this, but give the ability to read in a set of responses, and add additional responses, and print out all of the responses in alphabetical...

You will see that I'm asking you to think of yourself as president of the Pepsi Corporation. The key in the following situations is to determine what to do with the price of Pepsi based on your understand of price elasticity of demand. So, read each of these scenarios one by one and based on the information given decide if you want to raise, lower or leave the price of Pepsi the same. You don't have to be specific as to...

Ctri Question 3 (20 Marks) Lab 1-Zener Circuits and Applications Theory: Zener diode is designed to operate in reverse conduction. Zener breakdown occurs at a precisely defined voltage, allowing the diode to be used as a voltage reference or clipper. While Zener diodes are usually operated in reverse conduction, they may also be operated in cutoff and forward conduction. There are two different effects that are used in "Zener diodes". The only practical difference is that the two types have...
