Question

Part A - What is the effective resistance of the entire circuit?

Part B - If the loop containing R4, R5, and R6 is replaced by a single resistor R0, and R0 = R1 = R2 = R3 = R, what is the power dissapated across resistor R3?

Use Kirchhoff's Laws to find the current through   R2 and   R3.

Use Kirchhoff's Laws to find the current through     and   .

  Reff=R1+R2+R3 / R1(R2+R3) + R4+R5+R6 / R6(R4+R5)     Reff=R1 + R6 + R2R3 / (R2+R3) + R4R5 / R4+R5     Reff=R1 + R6 + R2+R3 / (R2R3) + R4+R5 / R4R5     Reff=R1(R2+R3) / (R1+R2+R3) + R6(R4+R5) / R4+R5+R6
