Question

Given the circuit below. R1 is 94 ohms, R2 is 114 ohms, R3 is 245 ohms, R4 is 145 ohms, R5 is 213 ohms, R6 is 260 ohms, R7 is 293 ohms, and R8 is 207 ohms. The potential difference between points a and b is 26 V.

A)What is the equivalent resistance of this circuit?

B)What is the potential difference across each resistor?Put in the value for R1 followed by a comma, the value for R2 followed by a comma, the value for R3 followed by a comma, ... and the value for R8.

C)What is the current through each resistor?Put in the value for R1 followed by a comma, the value for R2 followed by a comma, the value for R3 followed by a comma, ... and the value for R8.

Explanation / Answer

A) R1 + 1 / (1/R2 +1/(R3+R4) + 1/R5) + 1/ (1/R6 + 1/R7) + R8 = 501.137 ohm

B) total current = 26V/ 501.137 ohm = 0.05188 A.

Hence, the potential differences in volts are:

4.88, 3.24, 2.03, 1.21, 3.24, 7.147, 7.147, 3.24, 10.74

C) 51.88 mA, 28.42mA, 8.3mA, 15.21mA, 27.488mA, 24.39mA, 51.88 mA
