Part A: For the circuit shown below:

Without doing any calculations, which resistor will have the largest voltage drop across it$?$

Without doing any calculations, which resistor will have the biggest impact on the equivalent resistance?

Calculate the equivalent resistance $($as seen by the voltage source$),$ the total current $($ Is$)),$ and the voltage drop across each resistor.

Compare your results to your responses to Parts $($a$)$ and $($b$).$

Use Kirchhoff's Voltage Law to verify that your voltage drops calculated in Part $($c$)$ are correct.

Part B: For the circuit shown below, find all of the unknown values $($ V$($s$),$R$,$ and I $)$ if the total equivalent resistance seen by the voltage source is $9$Ohms.
