Question

Find the equivalent resistance of the combination of resistors shown above.

R 1+R 2+R3

(1 / R1+1 / R2+1 / R3)^{-1}

R1+(1 / R2+1 / R3)^{-1}

Find the equivalent resistance of the resistors shown above.

(1 / R1+1 / R2)^{-1}+R3+R4

R1+R2+(1 / R3+1 / R4)^{-1}

R1+R2+R3+R4

Assume the equivalent resistance in question 1 was 10 Ω and the equivalent resistance in question 2 was 40 Ω, and the same resistors were used for this new system. Determine the equivalent resistance of this system.
