Question

What is the total equivalent resistance in a parallel circuit that has one resistor of 11.1 ohms and a second resistor of 27.1 ohms?

Answer 1

We will have the following:

The equivalent resistance is given by:

`\begin{gathered} (1)/(R)=(1)/(11.1\Omega)+(1)/(27.1\Omega)\Rightarrow(1)/(R)=(3820)/(30081\Omega) \\ \\ \Rightarrow R=(30081)/(3820)\Omega\Rightarrow R\approx7.87\Omega \end{gathered}`

So, the equivalent resistance is approximately 7.87 Ohms.
