Chapter 6.1, Problem 4aT
The circuit at tight contains three identical bulbs and an ideal battery. Assume that the resistance of the switch, when closed, is negligible. Use the model we have developed to:
• predict the relative brightness of the bulbs in the circuit with the switch closed. Explain.
• predict how the brightness of bulb A changes when the switch is opened. Explain.

Consider the circuit configurations below, where two lightbulbs are connected to a single battery in different ways. Based on what you learned about parallel and series connections in lab, which of these two configurations would result in the light bulbs being the brightest? Fully explain your reasoning.
Imagine that you are given four 100Ω resistors to build a circuit. Your challenge is to use all four of the resistors in the circuit, but the circuit must have an overall equivalent resistance of 100Ω. Is this possible?
If so, draw a diagram of the circuit and explain how the connections result in a 100Ω equivalent resistance. If this is not possible, draw a diagram of a circuit involving all four resistors that has an equivalent resistance as close to 100Ω as is possible.
Consider the circuit below (picture attached)
How would you add a resistor with a resistance of 7.00 Ω to the circuit so that the current through the 3.0 Ω resistor is maximized? (This is already answered but I believe this correlates with part b. For this part the new resistor must be in parallel with the 4 ohm resistor)
By how much does the current through 3.0 Ω resistor increase when you do what was descibed above? (Must be in units of ampheres please.)
