The equation to find the value of R depends on the context. For resistors in series, the equation is R = R₁ + R₂ + R₃ + ..., while for parallel it is 1/R = 1/R₁+1/R₂ + 1/R₃ +.... In power calculations, the equation R = V²/P can be used.
To find the value of R, we can use various mathematical formulas depending on the context. For instance, in the context of circuits, the total equivalent resistance (R) of resistors in series is given by the equation R = R₁ + R₂ + R₃ + .... While for resistors in parallel, the equation is 1/R = 1/R₁+1/R₂ + 1/R₃ +....
In terms of power, the equation P = V²/R can be rearranged to R = V²/P to find the value of R. In case of calculations involving thermal resistance, the equations can be more complex and might require the use of other variables.

Sample Response: A rational number can be expressed as a whole number, a fraction, or decimal that has either terminating or repeating digits. A square root of a perfect square is rational. If it is none of these, then the number is irrational.
