A 6 ohm resistor is connected in series to a parallel connection of a 30 ohm resistor and a variable resistor R. What must be the value of R such that the power taken by the 6 ohm resistor will be equal to the power taken by R?

Answer:
You can find TOTAL RESISTANCE in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 + ... " Before we get into the calculations, remember what we said at the start of this section: "The total resistance of a parallel circuit is NOT equal to the sum of the resistors (like in a series circuit).
