Question

Part B
Your mischievous lab partner takes the resistor that you just experimented with and assembles it in a network with one other resistor inside a black box. When you tell him you don't care about his black box, he takes your lunch money and won't give it back until you can tell him the configuration of the resistors inside of the black box (parallel or series). (The lesson here is to feign polite interest in your totally lame lab partner.) Being an industrious physics student you connect the leads of the black box to your power source, voltmeter (in parallel), and ammeter (in series) and take the following simultaneous measurements.


Voltage (V) Current (mA)
2.775           14.48


Use the measurements to find the total resistance and infer from it what the arrangement must be. What do you answer to get your lunch money back?
*The answer will be either series or parallel




Part C
Now that you've served your lab partner and proven to all the class who the true physicist in the room is, the embarrassed lab partner wants revenge. He bets you double or nothing that you can't name the resistance of the resistor that he added to the one you experimented with. Using the information you obtained in parts A and B, predict this value of the resistance of the second resistor and make your lab partner rue the day he ever tangled with you!
