Please calculate the following: 1. You find an unlabeled resistor, and tests using a 9V battery yield a 100 mA current. What is the value of the resistor in ohms? 2. What is the power potentia

Please calculate the following:

1.    You find an unlabeled resistor, and tests using a 9V battery yield a 100 mA current. What is the value of the resistor in ohms?

2.    What is the power potential of the battery/resistor combo?

3.    A 500 W amplifier is intended for use with 4 Ω speakers. Instead 8 Ω speakers are connected. What will happen to the power? How about the current?

4.    How much current will the 8 Ω speakers draw form the amp?

5.    What is the voltage across the 8 Ω speaker?

Please post your calculations (show your work!) from the above exercise accompanied by your observations:

1.    Does anything remain confusing to you about working with power, voltage, and resistance?

2.    Are there any additional insights that you can share with your fellow classmates to help solidify these concepts?
