Question

In the combo circuit diagrammed, R1 = 19.2 Ω, R2 = 20.7 Ω, and R3 = 25.8 Ω. Find the equivalent resistance of the circuit.

Answer 1

Equivalent resistance: 13.589 Ω

Step-by-step explanation:

R series = R1 + R2 + R3 ...

`(1)/(R_(eq) ) = (1)/(R1) +(1)/(R2) +(1)/(R3) ...`

Find the equivalent resistance of the right branch of the circuit:

`R_(eq) = R_(2) +R_(3) \\R_(eq) = 20.7 + 25.8 = 46.5 ohms`

`(1)/(R_(eq) ) = (1)/(19.2) +(1)/(46.5)\\\\(1)/(R_(eq) ) = 0.0735887097\\\\R_(eq) = 13.5890411`
