brt se Part IV: Slightly more complex circuits A. Choose resistors Ri. Ra, Rs, R4, Rs, and Re and construct the circuit shown Uncertainty analysis for this circuit is EXTRA CREDIT Analyze the circuit to determine the equivalent resistance (this may take several steps of combining two resistors at a time). The first step-is-shown Show the subsequent steps taken in your analysis . Construct the circuit on the circuit board Measure the equivalent resistance Compare predicted and measured values (what is the discrepancy?) If the circuit is connected to a 9.0-V source, calculate AV across each resistor. . Ri 22.R Ri = 72. (3 220R Rs- 270- 39 12

Explanation / Answer

here,

R1 and R2 are in series , then equivalent resistance , R3' = R1 + R2 = 44 ohm

R3' and R3 are in parallel, the equivalent resistance R4' = R3 * R3' /( R3 + R3')

R4' = 44 * 34/( 44 + 34)

R4' = 19.2 ohm

R4' and R4 are in series , the equivalent resistance , R5' = R4 + R4' = 169.18 ohm

R5 and R5' are in parallel, the equivalent resistance R6' = R5 * R5'( R5 + R5')

R6' = 220 * 169.18/( 220 + 169.18)

R6' = 95.64 ohm

R6' and R6 are in series,

the Req of the circuit , Req = R6' + R6

Req = 134.64 ohm
